摘要
介绍了CdZnTe单元平面型射线探测器工作原理和模型,并对其输出的电流脉冲信号进行了理论计算和分析,结果表明输出电流信号约为1 nA/keV、脉冲上升时间为几十纳秒。讨论了在CdZnTe探测器前放电路设计过程中,采用PSpice软件进行模拟和仿真时,信号源选择采用电流源和电压源的参数计算方法。
The CdZnTe single-element planar detector＇s working theory and working model was introduced. The characteristics of the output signal was analyzed and computed. The result indicates the output current pulse is lnA/keV and risetime is a few ten nanoseconds. The compute method of the current source and voltage source parameters in simulate by PSpice is discussed.
