摘要: 描述了为兰州重离子加速器冷却储存环(HIRFL-CSR) 外靶实验系统硅微条阵列探测器而设计的前端电子学模块。该模块采用专用ASIC 芯片，可以处理96 路能量信号。对前端电子学模块的性能进行了测试，结果表明，该模块在0.1~0.7 V范围内的积分非线性好于0.3%；其电子学分辨好于0.45%，最大串扰小于10%；通道一致性测试结果好于1.3%；在室温下连续工作24 h 后，零点峰位最大漂移为1.48 mV。The silicon strip array detector is one of external target facility subsystems in the Cooling Storage Ring on the Heavy Ion Research Facility at Lanzhou (HIRFL-CSR). Using the ASICs, the front-end electronics module has been developed for the silicon strip array detectors and can implement measurement of energy of 96 channels. The performance of the front-end electronics module has been tested. The energy linearity of the front-end electronics module is better than 0.3% for the dynamic range of 0.1 ~ 0.7 V. The energy resolution is better than 0.45%. The maximum channel crosstalk is better than 10%. The channel consistency is better than 1.3%. After continuously working for 24 h at room temperature, the maximum drift of the zero-peak is 1.48 mV.Abstract: The silicon strip array detector is one of external target facility subsystems in the Cooling Storage Ring on the Heavy Ion Research Facility at Lanzhou (HIRFL-CSR).
