摘　　要：随着复合塑料闪烁体应用越来越广泛,各种厚度的复合塑料闪烁体应用场合越来越多。不同厚度和尺寸的塑料闪烁体由于射线在其内部能量沉积不同,给后续的电路的处理造成了比较大的困难。为了应对此问题,经过反复试验设计了此单电源运放电路,将不同能量、幅度的脉冲信号经过积分或者放大处理后,能更加有效地区分α脉冲和β脉冲,降低串道比的同时不影响探测效率。已应用于山西中辐核仪器有限责任公司不同厚度、尺寸的复合塑料闪烁体探测器便携式仪表当中。Phoswich scintillation is used more and more widely,the application of Phoswich scintillation of various thickness is increasing. The radiation in different thickness and size of the Phoswich scintillation will cause different energy deposition,this impulse processing will hard for next circuit. After many tests,this designed single supply amplifying circuit can deal with different energy deposition,and has better performance in dealing with α/β cross talk.
