摘要
介绍了百万像素硅像素探测器数据获取系统的设计。该系统根据实验需求,尤其针对硅像素探测器1.92 GB/s高带宽的数据读出指标进行设计,实现了数据高速稳定读出的目标,同时提供运行控制、在线事例组装、无损压缩、数据存储,以及抽样显示图像等功能。文中对系统进行了稳定性以及主要性能测试,测试表明系统长期运行稳定,最高读出带宽可达2.49 GB/s。
This paper introduces the design of the data acquisition system for the 1 million pixels silicon pixel detector. The DAQ system is designed specially according to the high bandwidth(1. 92 GB/s）feature of the pixel detector. It meets the requirement of high speed data readout,as well as consists the functions of run control,online event building,lossless data compression,data storage and real-time image display. After the test of the stability and main performance of the system,it is resulted that the readout bandwidth of the system is 2. 49 GB/s and the stability is great.
