摘　　要：A high resolution time measurement system with high data transfer rate was designed for the COLTRIMS (Cold Target Recoil-Ion Momentum Spectroscopy) system in Institute of Modern Physics,Chinese Academy of Sciences.It is used to measure the Time of Flight(TOF) with a high resolution for all 20 channels.Based on the PCI Extensions for Instrumentation(PXI) standard,the readout electronics system consists of one Clock-Trigger fan-out module and four TOF modules.Test results show that the system meets the demands of COLTRIMS,with a time resolution of better than 25 ps and a data transfer rate over 20 MB/s.A high resolution time measurement system with high data transfer rate was designed for the COLTRIMS （Cold Target Recoil-Ion Momentum Spectroscopy） system in Institute of Modem Physics, Chinese Academy of Sciences.
