【摘要】 针对北京正负电子对撞机(BEPCⅡ)逐束团(bunch-by-bunch)亮度监测系统需求,设计了高速亮度信号的采集、存储和显示系统。实现了4 ns束团间隔亮度信号的放大甄别、远距离传输、反符合判别,以及对应束团亮度信号的累加,利用乒乓存储技术解决了高数据产生率和CAMAC低数据读出率间的矛盾。测试结果表明,该设计能够满足BEPCⅡ4 ns间隔的逐束团亮度监测系统的要求。更多还原

【Abstract】 In order to meet the requirement of the fast luminosity monitor system of Beijing electron-positron collider(BEPCⅡ),a high-speed bunch-by-bunch luminosity signal processing and displaying system was designed.The techniques such as fast signal amplification,discrimination,long-distance signal transmission,anti-coincidence event judgment,counting for each bunch and ping-pang storage were involved effectively.The preliminary test result shows that the system can process and display the luminosity signals for bunches with 4 ns separation.更多还原
