摘要
介绍了基于以太网的GEM探测器高速数据采集系统的设计。该系统将GEM探测器输出的电荷信号转换为数字信号并写入FPGA进行分析和处理,处理后的数据通过千兆以太网进行传输。主机电脑接收以太网传输的电荷信号的位置信息,绘制电荷信号的位置分布图。实验测试表明:该系统能检测到探测器输出的位置信息并绘制出X射线信号的位置分布图。
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.
