摘要
为束流望远镜电子学系统研制一种可编程逻辑定标器。该NIM插件可同时记录30路ECL输入信号,采用增强型计算机并行端口读入方式,数据传输率达到2Mb/s。用于多丝正比室读出定位系统,在入射粒子计数率达到5×103/s测试条件下,获得稳定可靠的实验结果。
This scaler used programmable logic device is a design for the electronics of telescope system of the beam. The scaler can scale 30 ECL inputs at the same time. With the EPP (Enhanced Parallel Port) modes of the Parallel Port, the transmitted rate of data is 2MB/s. This scaler can be used in the position system of MWPC (Multi-Wires Proportional Chamber). Tested with particles of 5×10~3/s, the scaler gives a credible and stable result.
