摘要：

A readout electronics prototype system that can be used for high count rate gas detector was developed, which includes front-end board, data acquisition board and host computer. An advanced front-end readout application specific integrated circuit (ASIC) chip was utilized to develop the front-end board for realizing the measurement and analog-to-digital conversion of the detector signal. The field programmable gate array (FPGA) was used on the data acquisition board to realize the analysis, processing and transmission of the data. The host computer performs the sending of control instruction, the data receiving and storage. The prototype was verified through various tests, and it shows that the integral non-linearity of all channels is better than 0.24% in the input range of 2.2-99 fC. The test results with 55Fe radiation source are better than the results of commercial electronics under the same conditions, and this can meet readout requirements of GEM-TPC detector at 20 kHz count rate. © 2021, Editorial Board of Atomic Energy Science and Technology.
