The quantity that curve, counting rate and electrode collect charge is related；According to the counting rate and source range detector bias voltage signal
The plateau characteristic and examination threshold curve of acquisition source range detector；It is constant and discriminating threshold is constant in radiation source exposure intensity
In the case of, the curve changed with source range detector bias voltage according to counting rate is plateau characteristic, as shown in Figure 2
The plateau characteristic schematic diagram that bias voltage changes with counting rate, when bias voltage is more than a certain value, counting rate increases rapidly,
When bias voltage continues to increase, counting rate slightly increases with the raising of bias voltage, and is deposited there are one apparent level ground area B
；In level ground area B, if counting rate still slightly increases with the raising of bias voltage, showing as level ground has the gradient, can become plateau slope.
In the present embodiment, according to the plateau characteristic of source range detector, it may be determined that the work of source range detector

Between span compensation negative high voltage curve synoptic diagram；According in figure time-parameters Δ T and source range counting rate N determine the negative height of compensation
Pressure, wherein T0 is the time (IRC points of inflexion on a curve) that unit jumps heap or sub-critical point, and T1 refers to that power decline reaches among this
Time when range channel P6 occurs, the two difference are Δ T=T1-T0, and by being read on curve when P6 is non-to be occurred, (i.e. source is measured
When journey puts into operation) source range counting rate N, and determine compensation negative high voltage by the standard in table 1.In addition, the standard of parameter Δ T and N
Respectively 10min<ΔT<40min, 5000C/S<N<20000C/S.
Table 1
It should be noted that if intermediate range detector offset voltage is excessive, then make intermediate range electricity in stopping process
It is too fast to flow down drop, 1/2 intermediate range neutron flux measurement value is more than that definite value P6 is non-to be occurred ahead of time, source range technology mistake when putting into operation
Height exists and jumps heap risk；If intermediate range detector offset voltage is insufficient, the electric current that gamma-rays generates can not be filtered out, in
Between range electric current decline it is too slow, P6 it is non-appearance too late, there are the risks that source range cannot put into operation on time；If therefore one of ginseng
It measures (Δ T or counting rate N) and exceeds standard, then adjust the offset voltage in intermediate range channel according to table 1.
Step S104 assesses the performance of the detector according to the test data.

According to the plateau characteristic data of the intermediate range detector, judge whether the spy for needing replacing intermediate range detector
Head.
In the present embodiment, the degradation journey of intermediate range detector is judged by the plateau characteristic of intermediate range detector
It spends and is judged whether to need replacing probe according to degradation degree.The plateau characteristic of intermediate range detector as shown in Figure 4,
In high pressure V1To V3Between be plateau characteristic flat region, V0For rated voltage VnCorresponding to the 20% of corresponding saturation current
Voltage value；In order to characterize the slope of plateau characteristic, parameter P is defined,
Wherein, V0Represent the initial sensitivity of intermediate range detector, V0Higher, probe degradation degree is bigger.Work as plateau characteristic
Larger deformation or V occur for curve0It more than 70V, indicates that probe starts to degrade, needs every three months bent by being saturated plateau characteristic
Line monitoring probe whether aging；If plateau characteristic continues to deform or V0It is more than 6% more than 140V or P, then in next reactor
Probe is replaced in shutdown.
In addition, the long ion chamber for power range is similar with the intermediate plateau characteristic of compensated ionization chamber of range, but
It is different for the criterion of probe, if the plateau characteristic of power range long ion chamber deforms more serious or V0More than 30V
When, indicate that probe starts to degrade, to increase the frequency that probe aging aspect detects, such as every three months carries out a plateau characteristic
The analysis of curve；If curve continues deformation or V0It is more than 1.5% more than 60V or P, then replaces and visit in reactor shutdown next time
Head.
Further, the performance that the detector is assessed according to the test data further includes：
According to the ageing state of source range detector described in the discriminating threshold data assessment.
In embodiments of the present invention, the examination threshold curve of source range detector can sensitively reflect detector internal gas
The variation of amplification factor, can be as the foundation of assessment source range detector ageing state.Source range detector as shown in Figure 5
Examination threshold curve quantitative identifying, setting are carried out to the degradation of detector flat region for ease of the aging tendency of tracking detector
Parameter △ C,
When the degradation of △ C, i.e. △ C are more than 60%, show the variation of detector Gas Amplification Multiple, further reflect spy
Survey the aging conditions of device.
In addition, according to discriminating threshold point of inflexion on a curve, can also auxiliary judgment detector aging conditions.Such as shown in Fig. 6
The flow chart that detector aging is judged using discriminating threshold knee of curve, C indicates the degree of aging in discriminating threshold plateau area, n
Indicate the scale value of discriminating threshold potentiometer；According to threshold curve is screened, judgment curves whether there is inflection point, if there are inflection point and inflection points
Before examination value 3, then judge inflection point whether before examination value 2, if inflection point before examination value 2, and △ C (examination values 2
To examination value 4) be less than 60%, then it is 3 to adjust examination value, illustrates that source range channel and probe are normal；If inflection point examination value 2 it
Before, and △ C (examination value 2 to examination value 4) are not less than 60%, then judge aging of popping one's head in conjunction with high pressure plateau characteristic, need
Probe is replaced, and reacquires examination threshold curve；If inflection point is before 3, not before 2, △ C (examination value 3 to examination value 5) are no
Less than 60%, then judge aging of popping one's head in conjunction with high pressure plateau characteristic, need replacing probe, and reacquires discriminating threshold song
Line；If inflection point before 3 not before 2, and △ C (examination value 3 to examination value 5) be less than 60%, then adjust examination value be 4, and
In source, range measurement SAITB channel drifts are acceptable, and periodic test is carried out to source range Measurement channel SAITB；
If inflection point is not present in curve, and △ C (examination value 2 to examination value 4) are not less than 60%, then judge in conjunction with high pressure plateau characteristic
Probe aging, needs replacing probe, and reacquire examination threshold curve；If inflection point, and △ C (examination values 2 to Zhen is not present in curve
Not value 4) be less than 60%, then examination value is adjusted to 3, and acceptable in the drift of the channels SAITB, to the channels SAITB
Periodically checked；If there are inflection points for curve, but inflection point then replaces source range Measurement channel SAITB and lays equal stress on not before 3
New obtain screens threshold curve, and shows that the drift of the channels SAITB can not receive.
