英文摘要：

This paper introduces the design of high - speed data acquisition system for GEM detector based on Ethernet. The system converts the charge signal from the GEM detector into digital signal and writes it into the FPGA for analysis and processing. The processed data are transmitted through Gigabit Ethernet. The host computer receives the position information that charge signal from Ethernet transmission, and then drawing the position distribution map of charge signal. The experimental results show that the system can detect the position information of the X - ray signals successfully and plot the position distribution of the X - ray signals.
