摘　　要：针对CAS-LIBB单离子束装置设计了单离子束的模拟检测系统。论文详细分析了单离子束流的探测、放大、整形、JK触发器获取窄脉冲并展宽脉冲、F-V转换电路及信号的计数显示等几个部分的原理、参数的确定及相关的计算,检测精度99%以上。最后对检测系统进行测试和分析。The CAL-LIBB single ion-beam analog detecting instrument is designed, It mainly focus on picking-up the weak signals with the JK Flip-flop, widening the width of the pulse signals, translating the digital signals into analog signals and displaying the signals with the different frequency. The principles , parameters and methods of them have been discussed in detail. Finally we have tested the detecting systern and analyzed them.
