However, the detector sensitive body has low efficiency of detecting the counter-electron neutron.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.
Currently, detection of photoelectrons in the counter electron is usually achieved by IBD, and an organic scintillator is used as the detector sensitive body. In practical applications, organic scintillators for detecting photoelectrons in counter electrons mainly include liquid scintillators and plastic scintillators.
In practical applications, a gadolinium-or lithium-6-containing substance may be incorporated into a liquid scintillator to increase the probability of neutron capture by the scintillator. However, most liquid scintillators are toxic, volatile, or flammable, and thus, due to the above-mentioned peculiarities of physical and chemical properties of liquid scintillators, packaging, installation, and operation of liquid scintillator detectors are made difficult.
The physical and chemical properties of plastic scintillators are more stable than liquid scintillators, making plastic scintillator detectors relatively easy to operate and move.
In practical applications, a plurality of plastic scintillators are typically packaged as a plastic scintillator array. In practical applications, a gadolinium-containing substance may also be wrapped around the plastic scintillator array to increase the probability of capturing neutrons.
However, in both the liquid scintillator and the plastic scintillator, since the gadolinium doped in the liquid scintillator and the plastic scintillator has a large number of gamma (γ) rays released after capturing neutrons, high energy, and an indefinite emission direction, it brings certain difficulties for ray detection and data analysis, and therefore, the detection efficiency of the scintillator is not high, which directly causes difficulty in subsequently discriminating IBD events, and the discrimination efficiency is not high.
In practical applications, there is also a technical solution for capturing neutrons released in an IBD event by using a lithium-6 doped plastic scintillator to detect the distribution state of the photons in the counter electrons, but since highly concentrated lithium-6 is a control material, and its thermal neutron reaction cross section is small and natural abundance is low, compared with the above solution, there is no substantial improvement or improvement in the detection efficiency by using a lithium-6 doped plastic scintillator to detect the photons in the counter electrons.
Based on the above problems, the embodiment of the application provides a method for determining a distribution state of anti-electron neutrons, which is implemented by using a detector sensitive body array doped with boron-10 to obtain a particle signal set, and can improve the capture probability of neutrons in an IBD event process, so that the abundance and accuracy of the particle signal set transmitted by the detector sensitive body array can be improved, and further, the processing result obtained by processing the particle signals in the particle signal set and the accuracy of the distribution state of the anti-electron neutrons in the environment where the detector sensitive body array is located, which is determined based on the processing result, can be improved.

In one embodiment, the distribution state and/or the operation state of the nuclear reaction substance in the environment can be determined according to the distribution state of the counter-electron neutrons in the environment.
From the above, according to the method for determining the distribution state of the anti-electron neutrons provided by the embodiment of the application, because the thermal neutron capture cross section of boron-10 is large, the number of particle signals in a particle signal set acquired by a detector sensitive body array doped with boron-10 can be improved relative to the number of particle signals captured by a detector sensitive body doped with gadolinium in the related art; moreover, as the thermal neutron capture cross section of the boron-10 is larger, the capture efficiency of particle signals can be improved by doping the boron-10 with lower concentration in the detector sensitive body array, so that the negative influence of doping the boron-10 on the luminous efficiency of the detector sensitive body can be weakened; meanwhile, because the products of the reaction of the boron-10 and the neutrons are helium-4 and/or lithium-7, the detection efficiency of the particle signals is higher than that of gamma rays released after the neutrons are captured by gadolinium, so that the detection difficulty of the particle signals in the particle signal set can be reduced, and the detection efficiency of the particle signals can be improved.
On the other hand, due to the advantages of the detector sensitive body array in the embodiment of the present application, the accuracy of the processing result obtained by processing the particle signals in the particle signal set and the distribution state of the photoelectrons in the counter electrons in the environment where the detector sensitive body array is located, which is determined based on the processing result, can be directly improved.
The detection of the reactor interior electron neutrinos is a nuclear security technology recommended by the International Atomic Energy Agency (IAEA), and the method for determining the distribution state of the reactor interior electron neutrinos provided by the embodiment of the application can realize non-intervention monitoring on the reactor.
Based on the foregoing embodiment, in the method for determining a distribution state of photoelectrons in an anti-electron provided in the embodiment of the present application, the detector sensitive body includes a plastic scintillator doped with boron-10, two light guides respectively connected to two ports of the plastic scintillator in a sealing manner, and two photomultiplier tubes respectively connected to the two light guides in a sealing manner; the plastic scintillator is hexagonal prism shaped.
Fig. 2 is a front view of a plastic scintillator provided in an embodiment of the present application. As shown in fig. 2, the detector sensitive body 2 includes a plastic scintillator 201 doped with boron-10, two light guides 202 hermetically connected to two ports of the plastic scintillator, respectively, and photomultiplier tubes 203 hermetically connected to the two light guides 202, respectively.
Fig. 3 is a top view of a plastic scintillator provided in an embodiment of the present application. Fig. 4 is a side view of a plastic scintillator provided by an embodiment of the present application. As can be seen from fig. 3 and 4, the plastic scintillator 201 is a regular hexagonal prism shape.
In one embodiment, the plastic scintillator 201 may be a solid hexagonal prism shape.
In an embodiment, the shape and size of the plastic scintillator 201 can be determined or adjusted according to actual detection requirements, which is not limited in the embodiments of the present application.
In one embodiment, the light guide 202 may be a shaped light guide, which may be made of an acrylic material.
In one embodiment, the photomultiplier 203 may convert a weak optical signal emitted from the plastic scintillator 201 into an electrical signal, thereby improving the capture efficiency of the optical signal emitted from the plastic scintillator 201.
Fig. 5 is a schematic structural diagram of a detector sensitive body array according to an embodiment of the present application. As shown in fig. 5, the hexagonal prism shape of the detector sensitive bodies allows a close arrangement between the plurality of detector sensitive bodies, and the cross section of the arranged plurality of detector sensitive bodies may be also a hexagonal prism shape in terms of a macroscopic view. Therefore, under the condition that the volume of the detector sensitive body array is the same, the detector sensitive bodies with more number can be accommodated, and the detection efficiency of the detector sensitive body array can be improved.
Accordingly, the acquisition of the particle signal set transmitted by the boron-10 doped detector sensitive body array can be realized by the following modes:
and acquiring a particle signal set transmitted by the plastic scintillator through an electric connection channel between the particle signal set and the photomultiplier.
In an embodiment, an electrical connection channel is provided between a hardware interface of the electronic device and two photomultiplier tubes disposed at two ends of each plastic scintillator, so as to obtain two paths of particle signals output at two ends of the plastic scintillator, and thus, when the number of the plastic scintillators is K, the electronic device can obtain 2K particle signals through electrical connection with the photomultiplier tubes, and the 2K particle signals can be a particle signal set. Wherein K is an integer greater than 1.
As can be seen from the above, in the method for determining the distribution state of the photoelectrons in the counter-electrons provided in the embodiment of the present application, the detector sensitive bodies include the hexagonal prism-shaped plastic scintillator doped with boron-10, so that when a plurality of detector sensitive bodies are combined, the arrangement tightness between the detector sensitive bodies can be improved.
In the related art, for a scintillator doped with lithium-6, the doping concentration of lithium-6 needs to be increased in order to obtain higher neutron detection efficiency, however, the higher doping concentration of lithium-6 affects the light emission efficiency of the scintillator. In the embodiment of the application, because the thermal neutron capture cross section of the boron-10 is larger, the neutron detection efficiency can still be effectively improved under the condition of lower doping concentration of the boron-10, so that the negative influence on the luminous efficiency of the plastic scintillator due to doping of the boron-10 can be weakened; meanwhile, the two light guides respectively connected with the two ports of the plastic scintillator in a sealing manner can improve the collection efficiency of particle signals; on the other hand, the detection and conversion efficiency of the weak light signal emitted by the plastic scintillator can be improved through the photomultiplier.
In addition, when the detector sensitive body array provided by the embodiment of the application detects the anti-electron neutrino, the neutron detector does not need to be additionally arranged on the periphery of the detector sensitive body array, so that the complexity of the design of a detection system comprising the detector sensitive body array can be reduced, and the difficulty of subsequent data acquisition and processing is further reduced.
Based on the foregoing embodiment, in the method for determining a distribution state of photoelectrons in an anti-electron provided in the embodiment of the present application, based on a processing result, a distribution state of photoelectrons in an anti-electron in an environment where a detector sensitive body array is located may be determined by:

In one embodiment, the processing result may include converting the particle signals in the particle signal set, sampling the digital representation after quantization coding, for example, converting the optical signals in the particle signal set into electrical signals, for example, voltage signals, and then sampling and quantization coding the voltage signals to obtain the digital representation of the voltage signals.
In one embodiment, the pulse discrimination results may include the result of whether the set of particle signals includes an optical signal due to the boron-10 capture to a neutron.
In one embodiment, the pulse discrimination results may include the result of the number or density of optical signals contained in the set of particle signals resulting from the capture of neutrons by boron-10, that is, the pulse discrimination results may be indicative of the result of the number or frequency of IBD events occurring.
In one embodiment, the pulse discrimination result may be obtained by:
and obtaining a current signal based on the voltage signal in the processing result, performing integral calculation on the current signal based on time to obtain charge data, and then realizing PSD processing on the processing result by a charge comparison method so as to obtain a pulse identification result. Exemplarily, the PSD processing can be implemented by equation (1):
f PSD = (Q long -Q short )/Q long (1)
in formula (1), f PSD Is a PSD factor which is used for representing the discrimination ability of neutron signals and positron signals in the particle signal set; q long Integrating the corresponding charge data for the waveform long gate charge; q short The corresponding charge data is short-gated for the waveform.
In one embodiment, the pulse discrimination result may be f in formula (1) PSD
Fig. 6 is a schematic diagram of a principle of obtaining a pulse discrimination result according to an embodiment of the present disclosure, and as shown in fig. 6, a curve 601 may be an integration result of the charge data, and the pulse discrimination capability of the PSD may be adjusted and improved by adjusting lengths of the long gate 602 and the short gate 603.
In one embodiment, whether the counter electron neutron exists in the environment can be determined based on the pulse discrimination result, and the number of times or the probability of the counter electron neutron appearing can also be determined.
As can be seen from the above, in the method for determining the distribution state of the anti-electron neutrons provided in the embodiment of the present application, the PSD processing is performed on the processing result to obtain the pulse discrimination result, so that the neutron signal and the positron signal in the particle signal set are accurately distinguished by using the PSD technology, and the pulse discrimination result can accurately reflect the number and the distribution state of the neutrons and the positron signal in the environment, and further the accuracy of the distribution state of the anti-electron neutrons in the environment determined based on the pulse discrimination result can be improved, and the accuracy of discrimination of the IBD event is improved.
Based on the foregoing embodiment, in the method for determining a distribution state of a counter electron neutron, particle signals in a particle signal set are processed to obtain a processing result, which may be implemented in the following manner:
counting the particle signals in the particle signal set to obtain a statistical result; and carrying out sampling quantization processing on the particle signals based on the statistical result to obtain a processing result.
In one embodiment, the statistical result may be obtained by:
counting the number of at least part of particle signals in the particle signal set to obtain a statistical result; for example, the at least part of the particle signals may include particle signals output by at least part of the detector sensors in the detector sensor array, and may further include particle signals received by the electronic device within a specified time period, where the electronic device may set time information for the particle signals when it receives the particle signals, and the time information may be associated with a clock cycle of the electronic device.
In one embodiment, the processing result may be obtained by any one of the following methods:
grouping the particle signals in the particle signal set based on the statistical result to obtain a grouping result, and then performing sampling quantization processing on each particle signal in the grouping result to obtain a processing result; illustratively, the number of particle signals in each grouping result may be the same or different.
Determining a strategy for grouping the particle signal set based on the quantity of the statistical results, and then grouping the particle signals in the particle signal set according to the strategy to obtain the grouping result; for example, the above strategies may include a strategy of equalizing the data processing capability of the electronic device with the generation speed of the particle signals, for example, when the number of the particle signals received in a unit time exceeds the data processing speed range of the electronic device, the particle signal sets may be grouped and the particle signals in the grouping result may be sequentially subjected to sampling and quantization processing, and when the number of the particle signals received in the unit time is within the data processing speed range of the electronic device, the particle signals in the particle signal sets may be directly subjected to sampling and quantization processing without being grouped.
A sampling frequency and a quantization bit number are determined based on the statistical result, and then the particle signal is sampled and quantized based on the sampling frequency and the quantization bit number.
Therefore, in the method for determining the distribution state of the anti-electron neutrons provided by the embodiment of the present application, the particle signals in the particle signal set are counted, so that the statistical result can comprehensively and accurately reflect the information such as the number, the amplitude, the density and the like of the particle signals in the particle signal set; in this way, when the particle signals are subjected to sampling quantization processing based on the statistical result, not only can the particle signals be subjected to targeted sampling quantization processing, but also the number of the particle signals in the particle signal set and the data processing capacity of the electronic equipment can be balanced, so that the particle signal sampling quantization processing is targeted, and the accuracy and effectiveness of the processing result are improved.
Based on the foregoing embodiment, in the method for determining a distribution state of a neutron in an anti-electron, provided by the embodiment of the present application, the particle signals in the particle signal set are counted to obtain a statistical result, which may be implemented in the following manner:
distributing particle signals in the particle signal set to obtain at least a first signal set; and counting particle signals in the first signal set and associated with the detector sensitive bodies in the detector sensitive body array to obtain a statistical result.
Wherein the number of particle signals in the first set of signals is the same as the number of particle signals in the set of particle signals.
In one embodiment, the particle signals in the set of particle signals may be power divided, resulting in at least a first set of signals.
In one embodiment, the signal distribution circuit may be designed and the distribution operation of the particle signals in the particle signal set is realized by the signal distribution circuit. Fig. 7 is a schematic structural diagram of a signal distribution circuit according to an embodiment of the present application, and as shown in fig. 7, a resistor R 0 Branch ofThe path may be an input terminal of the particle signal set, and the particle signal set may be input to the resistor R 1 A first branch, thereby obtaining a first signal set; illustratively by adjusting the resistance R 0 And a resistance R 1 The resistance value of (2) can enable the amplitude of the particle signal in the first signal set to meet the amplitude requirement of subsequent circuit processing.
In one embodiment, the particle signals associated with the detector sensitive bodies in the detector sensitive body array may include particle signals respectively output by two ports of each detector sensitive body.
In one embodiment, the statistical result may be obtained by any one of the following methods:
judging the particle signals associated with the kth detector sensitive body in the first signal set, and counting the particle signals output by the kth detector sensitive body if the particle signals associated with the kth detector sensitive body are determined to be two, namely the particle signals output to the electronic equipment by the kth detector sensitive body are two; if it is determined that the particle signals associated with the kth detector sensitive volume are less than two, that is, the kth detector sensitive volume does not output a particle signal or outputs only one particle signal, then the particle signals associated with the kth detector may not be counted. Wherein K may be an integer greater than or equal to 1 and less than or equal to K.
For example, a hardware port of the electronic device may be electrically connected to each detector sensitive body, the electronic device may number the particle signal received by each hardware port, and the number information may represent an address of the hardware port, or may represent a number, a position, or a setting relationship of the detector sensitive body electrically connected to the hardware port in the detector sensitive body array with respect to other detector sensitive bodies. The corresponding or incidence relation between the particle signals and the sensitive body of the detector can be rapidly distinguished through the serial numbers, so that a basis is provided for statistics of the particle signals associated with the sensitive body of the detector.
As can be seen from the above, in the method for determining a distribution state of anti-electron neutrons provided in the embodiment of the present application, particle signals in a particle signal set are distributed to obtain a first signal set, and the number of the particle signals in the first signal set is the same as the number of the particle signals in the particle signal set, so that a foundation is laid for the accuracy of a statistical result obtained by counting the particle signals in the first signal set; and particle signals associated with the detector sensitive bodies in the detector sensitive body array in the first signal set are counted, so that tracking identification of the particle signals output by each detector sensitive body can be realized, and statistical processing of fine granularity of the particle signals in the particle signal set is realized.
Based on the foregoing embodiment, in the method for determining a distribution state of photoelectrons in anti-electrons provided in the embodiment of the present application, statistics may be performed on particle signals associated with detector sensitive bodies in an array of detector sensitive bodies in a first signal set, and the method may be implemented in the following manner:
if the amplitude of the particle signal associated with the kth detector sensitive body in the detector sensitive body array in the first signal set is greater than or equal to the first threshold, the particle signals associated with the kth detector sensitive body are counted.
Wherein k is an integer greater than or equal to 1.
Illustratively, K may be less than or equal to K.
For example, if the amplitude of the particle signal associated with the kth detector sensitive volume in the first signal set is less than the first threshold, the particle signal may be discarded, and all particle signals associated with the kth detector sensitive volume may also be discarded.

Fig. 9 is a schematic structural diagram of a double-ended coincidence unit provided in the embodiment of the present application, and as shown in fig. 9, the double-ended coincidence unit 801 may include a logic unit capable of implementing and operation, where a particle signal associated with a first port of a kth detector sensitive body may be input through a first input port 8011, a particle signal associated with a second port of the kth detector sensitive body may be input through a second input port 8012, and a double-ended coincidence result may be obtained through an and operation of the double-ended coincidence unit 801 on the two particle signals through an output port 8013. That is to say, the double-end coincidence circuit 801 is configured to determine validity of two particle signals output by the kth detector sensitive body, and when the particle signals output by the two ports of the kth detector sensitive body are both valid signals, the particle signals can be continuously processed by the subsequent circuit unit.
As shown in fig. 8, the double-ended coincidence result output from the double-ended coincidence unit 801 may be input to the multi-way flip-flop unit 802. Fig. 10 is a schematic structural diagram of a multi-way trigger unit provided in the embodiment of the present application, and is described in fig. 10 by taking an example that a double-ended coincidence result includes data corresponding to eight detector sensitive bodies, as shown in fig. 10, a first adder 8021 to a fourth adder 8024 of a multi-way trigger unit 802 are respectively used to perform addition calculation on two adjacent data in the double-ended coincidence result; the fifth adder 8025 may perform addition calculation on the addition results output by the first adder 8021 and the second adder 8022, the sixth adder 8026 may perform addition calculation on the addition results output by the third adder 8023 and the fourth adder 8024, the result output by the fifth adder 8025 and the result output by the sixth adder 8026 may be continuously performed by the seventh adder 8027 to obtain an addition result of a double-ended coincidence result, the comparator 8028 may perform the addition result of the double-ended coincidence result and a preset threshold, if the addition result of the double-ended coincidence result is greater than or equal to the preset threshold, the comparator outputs the addition result of the double-ended coincidence result to the first port of the enable trigger 8029, and if the signal input by the second port of the enable trigger 8029 is an enable signal, the enable trigger 8029 may output the addition result of the double-ended coincidence result; for example, if the addition result of the two-terminal coincidence result is less than the preset threshold, the comparator 8028 may not output the addition result of the two-terminal coincidence result to the enable flip-flop 8029.
As shown in fig. 8, after the multi-channel trigger unit 802 outputs the addition result of the two-port coincidence result to the trigger signal generation unit 803, the trigger signal generation unit 803 may generate a trigger signal by generating a pulse or by performing a processing operation such as stretching on the pulse.
As shown in fig. 8, after the trigger signal generation unit 803 generates the trigger signal, the trigger time recording unit 804 may record the generation time of the trigger signal.
Fig. 11 is a schematic diagram of a data storage structure of a trigger time in a trigger signal generation unit according to an embodiment of the present application. As shown in fig. 11, the trigger time generating unit may store the generation time of the trigger signal through a 128-bit digital signal, wherein the 128-bit trigger time may be divided into four segments of data, the bit number of each segment of data is 32 bits, and in the 32-bit data, the 0 th bit to the 27 th bit may be a data bit, and the 28 th bit to the 31 th bit may be an identification bit.
As shown in fig. 11, if the 28 th to 31 th bits in the 32 th bit data generated by the trigger signal generation unit are 0011, respectively, the 0 th to 27 th bits indicating that the 32 th bits store the 28 th to 55 th bits of the gating signal count; if the 28 th to 31 th bits in the 32-bit data are 0111 respectively, the 0 th to 27 th bits of the 32-bit data are stored with the 0 th to 27 th bits of the gating signal count; if the 28 th to 31 th bits in the 32-bit data are 0001 respectively, the 0 th to 27 th bits of the 32-bit data store the 28 th to 55 th bits of the clock cycle signal count; if the 28 th to 31 th bits in the 32-bit data are 0101, respectively, the 0 th to 27 th bits of the 32-bit data store the 0 th to 27 th bits of the clock cycle signal count.
Illustratively, the gating signal count generated by the trigger signal generation unit may be obtained by concatenating the 0 th to 27 th bits of the above gating signal count and the 28 th to 55 th bits of the gating signal count; the clock period signal generated by the trigger signal generating unit can be obtained by splicing the 0 th to 27 th bits counted by the clock period signal and the 28 th to 55 th bits counted by the clock period signal.
As shown in fig. 8, the double-end coincidence result output by the double-end coincidence unit 801 may also be output to the counting unit 805, so as to count the number of valid particle signals output in unit time.
In fig. 8, before the data processing is started and after the data processing is finished, the states of the respective data processing units can be reset by the reset unit 806.
As can be seen from the above, the trigger signal is generated by performing hierarchical diversity processing on the particle signals in the first signal set through the programmable logic module, so that the consistency between the trigger signal and the particle signals in the first signal set can be improved, and the probability of false triggering and missed triggering can be reduced.
In one embodiment, the sampling and quantizing process of the particle signals in the second signal set is triggered when the trigger signal is generated, and the sampling and quantizing process of the particle signals in the second signal set may not be executed when the trigger signal is not generated.
From the above, the particle signals in the particle signal set are distributed to obtain the second signal set, the particle signals in the second signal set are sampled and quantized based on the trigger signal to obtain the processing result, and the trigger signal is generated based on the statistical result of the particle signals in the first signal set, so that different data processing processes for different signal sets are realized, data coupling between the trigger signal generation process and the sampling and quantization process is reduced, and the sampling and quantization processing efficiency is improved; furthermore, by allocating the set of particle signals to the first signal set and the second signal set, consistency between the trigger signal and the sampling quantization process can also be improved.
Based on the foregoing embodiment, in the method for determining a distribution state of an anti-electron neutron, the particle signals in the second signal set are subjected to sampling quantization processing based on the trigger signal, and the method can be further implemented in the following manner:
determining a delay time; delaying the second signal set based on the delay time to obtain a delayed second signal set; and triggering the particle signals in the delayed second signal set to be subjected to sampling quantization processing based on the trigger signal.
In one embodiment, the delay time may be determined according to the data processing speed of the programmable logic module in the foregoing embodiment; illustratively, the delay time may be determined according to a data processing speed of the programmable logic module and a flow of data processing logic from the first set of signals to the generation of the trigger signal.
In one embodiment, the second set of signals may be delayed based on the generation time by a signal extension line, resulting in a delayed second set of signals.
Fig. 12 is a schematic diagram of a circuit structure for obtaining a processing result according to an embodiment of the present application. As shown in fig. 12, the signal obtaining unit 1201 may be electrically connected to each photomultiplier in the detector sensitive body array, so as to obtain particle signals output by two ports of each detector sensitive body, and obtain a particle signal set; the signal distribution unit 1202 may distribute the set of particle signals through a circuit as shown in fig. 7, and transmit the first set of signals to the discrimination unit 1203 and the second set of signals to the signal delay unit 1204.
For example, the screening unit 1203 may determine the amplitude of the particle signal associated with the kth detector volume in the first signal set based on a first threshold, thereby determining the validity of the particle signal output by the kth detector volume. The programmable logic module 8 can process the particle signal output by the discrimination unit 1203 through the circuit shown in fig. 8, so as to generate a trigger signal, and send the trigger signal to the waveform sampler 1205.
For example, if the waveform sampler 1205 is in the sampling process, it may generate a busy state signal, and send the busy state signal to the enable flip-flop of the multi-trigger unit in the programmable logic module 8, so that it suspends generating the trigger signal; if the sampling process of the waveform sampler 1205 is finished or no sampling operation is performed, an idle state signal may be generated and sent to the enable trigger, enabling generation of the trigger signal. The busy state signal may be an enable signal input to the enable flip-flop in the foregoing embodiment.
For example, the waveform sampler may sample and quantize the particle signals in the second signal set delayed by the signal delay unit 1204 under the trigger of the trigger signal, determine the sampling and quantizing result as the processing result, and then send the processing result to the computer 1206, so that the computer 1206 performs offline processing on the processing result.
For example, an electrical connection channel may be established between the computer 1206 and the programmable logic module 8, so as to receive the trigger time generated by the programmable logic module 8.
Illustratively, the computer 1206, upon receiving the processing result and the trigger time, may correlate the processing result and the trigger time to lay a data foundation for subsequent execution of the PSD processing.
As can be seen from the above, in the method for determining a distribution state of an anti-electron neutron, after the delay time is determined, the second signal set can be delayed based on the delay time to obtain a delayed second signal set, so that time synchronization can be maintained between the delayed second signal set and the trigger signal; therefore, when the particle signals in the delayed second signal set are subjected to sampling quantization processing based on the trigger signal, the consistency between the processing result and the particle signal set can be improved.

According to the device for determining the distribution state of the counter-electron neutrons, the thermal neutron capture cross section of the boron-10 is large, so that the number of particle signals in a particle signal set obtained by a detector sensitive body array doped with the boron-10 can be obviously improved; moreover, as the thermal neutron capture cross section of the boron-10 is larger, the capture efficiency of particle signals can be improved by doping the boron-10 with lower concentration in the detector sensitive body array, so that the influence of doping the boron-10 on the luminous efficiency of the detector sensitive body is reduced; meanwhile, because the products of the reaction of the boron-10 and the neutrons are helium-4 and/or lithium-7, the detection efficiency of the particle signals is higher than that of gamma rays released after the neutrons are captured by gadolinium, so that the detection difficulty of the particle signals in the particle signal set can be reduced, and the detection efficiency of the particle signals can be improved.
