Description

Gas electron multiplier (GEM) is the most promising position sensitive gas detector. The new generation of readout electronics system includes APV25 front-end card, multi-purpose digitizer (MPD), VME controller and Linux-based acquisition software DAQ. The construction and preliminary test of this readout system were finished, and the ideal data with the system working frequency of 40 MHz and 20 MHz were obtained. The long time running test shows that the system has a very good time-stable ability. Through optimizing the software configuration and improving hardware quality, the noise level was reduced, and the signal noise ratio was improved. (authors)
