摘　　要：本文介绍了兰州重离子加速器冷却储存环(HIRFL-CSR)外靶实验读出电子学预研系统的设计。该系统可实现TOF墙探测器、中子墙探测器、多丝漂移室(MWDC)等的读出。基于前沿定时及使用TOT技术分别进行时间和电荷测量,从而对前沿定时带来的时间-幅度游走效应进行修正。该系统基于工业智能仪器总线PXI进行设计,提高了数据传输带宽,并保证了系统的可扩展性。目前已完成基本单元模块的实验室电子学测试,以及与探测器的初步联合测试,验证了各项功能指标。A prototype of the readout electronics system was designed for the external experiment in HIRFL‐CSR .This system is responsible for the readout of the TOF wall detector ,the neutron wall detector and the MWDC .The time measurement was based on leading edge discrimination ,while the TOT method was employed in charge meas‐urement ,and this made the time‐walk to be corrected . The electronics was designed based on the PXI standard in order to guarantee that this system has a high data transfer rate and a good flexibility . T he laboratory tests and preliminary commissioning tests with the detectors were conducted ,which indicate the system functions are good .
