Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with attached drawing to the present invention Each embodiment be explained in detail.However, it will be understood by those skilled in the art that in each embodiment party of the present invention In formula, in order to make the reader understand this application better, many technical details are proposed.But even if without these technical details And various changes and modifications based on the following respective embodiments, the application technical solution claimed also may be implemented.
The first embodiment of the present invention is related to a kind of strong measuring devices of electronic beam current, as shown in Figure 1, for measuring electronics The electronic beam current of beam Medical Devices is strong, the electron beam Medical Devices include for launching electronics beam 3 electron beam launcher 1, The line needle 2 being connect with electron beam launcher 1.
And in order to realize that the electron beam 3 to above-mentioned electron beam launcher 1 flows strong test, as shown in Figure 2 and Figure 8, this reality It includes sensing device 4 and signal processing apparatus 5 that the electron beam 3 for applying mode, which flows strong test equipment,.Wherein, the induction of sensing device 4 is logical Magnetic field caused by the electron beam 3 of line needle 2 is crossed, and exports electric current after sensing magnetic field, it is defeated to generate electric signal by electric current Give signal processing apparatus 5.Signal processing apparatus 5 and sensing device 4 are electrically connected, and receive the telecommunications that sensing device 4 exports Number, and flowed by force according to the electron beam 3 that the Strength co-mputation of electric signal obtains flowing through line needle 2.
Thus it is not difficult to find that due to being equipped with sensing device 4 and signal processing apparatus 5, the electron beam 3 of line needle 2 generates magnetic , 4 induced magnetic field of sensing device, and cause electric current after induction, electric current generates electric signal and is conveyed to signal processing apparatus 5.Letter Number processing unit 5 receives the electric signal being amplified, and show that the electron beam 3 of line needle 2 flows by force according to the intensity of electric signal, passes through Such mode can accurately measure the electron beam 3 that 3 Medical Devices of electron beam are issued and flow by force.
Specifically, in the present embodiment, as shown in Fig. 2, sensing device 4 includes signal probe 41 and conducting wire 42.Its In, signal probe 41 is used to incude magnetic field caused by the electron beam 3 by line needle 2, and causes electricity after sensing magnetic field Stream, while electric probe or magnetic probe can be used in the signal probe 41, to meet different testing requirements.Also, in order to more Good measures electron beam 3 by magnetic field caused by line needle 2, and as a preferred solution, signal probe 41 can be equipped with more It is a.It, can be by conducting wire 42 by signal in addition, be sent to signal processing apparatus in order to the electric current for being exported signal probe 41 Probe 41 is electrically connected with signal processing apparatus, and signal probe 41 causes electric current after sensing magnetic field, generates telecommunications Number, electric current is conveyed to signal processing apparatus 5 by conducting wire 42.Meanwhile in the present embodiment, microstrip line can be used in conducting wire 42, Since microstrip line has the characteristics that small in size, bandwidth, physical structure are elongated, make convenient for being disposed on line needle 2 With.
Also, it is worth mentioning, as shown in figure 3, in the present embodiment, microstrip line is strip structure, and microstrip line is Complete docile is on the inner wall of line needle 2, certainly alternatively, as shown in figure 4, microstrip line is also cylindrical in shape docile In on the inner wall of line needle 2, so that signal probe 41 more convenient can be electrically connected with microstrip line.
In addition, alternatively, as shown in figure 5, microstrip line can also docile completely on the outer wall of line needle 2. Specifically, micro- as shown in fig. 6, the microstrip line can be equally the structure of strip or tubular, and when microstrip line is tubular structure The outer wall of line needle 2 can be directly coated on line, so that the setting of microstrip line is more convenient.
It should be noted that in the present embodiment, microstrip line is only illustrated by taking strip and tubular as an example, certainly in reality During the use of border, microstrip line can also be using other form dociles on the inner wall or outer wall of line needle 2, for example, micro- It is wrapped on the outer wall of line needle 2 with the mode that spiral can also be used in line, so as to allow microstrip line to be not easy to fall from line needle 2 It falls.And it is not illustrated one by one in the other forms to microstrip line in the present embodiment.
In addition, as shown in Figure 1, generated electric signal is also corresponding since 3 stream of pulses of electron beam is by force in microampere magnitude It is weaker, if need accurately electric signal transmitted by sensing device is handled, the signal being previously mentioned in present embodiment Processing unit 5 includes signal amplification circuit 51, oscillograph 52 and processor 53.Wherein, signal amplification circuit 51 as shown in fig. 7, It is mainly made of capacitor C, resistance R and amplifier P, and the selection of capacitor C, resistance R and amplifier P can be according to actual electron beams 3 stream is selected by force, and signal amplification circuit 51 is electrically connected with sensing device 4 and oscillograph 52 respectively, and oscillograph 52 are also electrically connected with processor 53.During practical application, signal amplification circuit 51 can be first passed through and receive sensing device 4 Conducting wire 42 in the electric signal of output, i.e. signal amplification circuit 51 and sensing device 4 is electrically connected, the electricity that receiving wire 42 transmits Signal.And amplify the electric signal received, and exported after amplification to oscillograph 52, by oscillograph 52 according to being received The electric signal arrived generates the waveform for the electric signal, and processor 53 can be flowed through according to the waveshape generated of oscillograph 52 The electron beam 3 of line needle 2 flows by force.
Specifically, the stream of the electron beam 3 in line needle 2 is Ie by force, the electric current that microstrip line is drawn, the electric signal of generation with Voltage signal output, the voltage value of the voltage signal are that Vin is directly proportional to the strong Ie of stream of electron beam 3 in line needle 2, they it Between proportionate relationship are as follows: Vin=k*Ie, wherein k is the number of a very little, and has the guiding principle amount of resistance.In addition, signal amplification circuit 51 amplification factor is M, and the voltage value of amplified voltage signal is Vm, and oscillograph 52 receives amplified voltage signal The waveform that value Vm is generated is a square wave, and the relationship of you can get it square wave Vm and voltage Vin are Vm=Vin*M.
Therefore, according to the voltage value Vin of above-mentioned electric signal, amplification factor M, amplified voltage signal value Vm and stream Relationship between the parameters such as strong Ie, can obtain Ie=Vm/ (M*k).Calculate flow strong Ie when, by each parameter value bring into formula and It can.A practical calculating case is enumerated below, and when the square wave Vm of oscillograph 52 is 200mV, the value of M is that 1000, k is 0.00005 Europe When nurse, it can show that the strong Ie of stream is 10mA at this time.
Through the above it is not difficult to find that can accurately calculate the stream of electron beam 3 for flowing through line needle 2 in this manner By force.
Electric signal amplification to export by signal amplification circuit 51 by sensing device, and oscillograph 52 will be amplified Electric signal generates matched waveform, and final process device 53 goes out electron beam 3 according to waveshape and flows by force.
