在HIRFL-CSR重离子外靶实验中，采用多丝漂移室测量带电粒子的漂移时间，以获取径迹信息。该128通道高精度时间测量模块设计用于执行时间数字化。数据传输基于PXI接口，以保证高数据速率。测试结果表明，100 ps的分辨率与数据传输速率高达40 MBps已实现，该模块也已被证明是功能良好的探测器通过调试测试。关键词：高精度，时间测量，PXI，数据传输，调试测试。
In the external target experiment for heavy ion collisions in the HIRFL -CSR, Multi-Wire Drift Chambers are used to measure the drift time of charged particles to obtain the track information. This 128 -channel high precision time measurement module is designed to perform the time digitization. The data transfer is based on a PXI interface to guarantee a high data rate. Test results show that a 100 ps resolution with a data transfer rate up to 40 MBps has been achieved; this module has also been proven to function well with the detector through a commissioning test. Keyword : high precision, time measurement, PXI, data transfer, commissioning test.
