摘要
采用波形积分法研制了用于脉冲堆裂变总数测量的闪烁体探测器,采用脉冲峰和脉冲坪信号分路引出的设计,同时测量裂变率相差较大的脉冲峰和脉冲坪。该探测器具有线性电流大、测量范围宽的特点,在测量小产额脉冲时更具优势。该裂变总数测量方法与其他方法获得的结果一致。
The scintillator detector used to measure the total fission numbers of burst reactors was designed by the method of waveform integral.The scintillator detector has the characteristics of high linear currents and wide measurement ranges.Because of shunt circuit design in signal output,the detector can measure the peak and the plateau of bursts at the same time despite of the marked difference in fission rates between them.The results of this method are according with those of other methods.It is superior in measuring low yield bursts.
