Development of tune measurement system for HLS-Ⅱ storage ring
-
摘要: 介绍了在合肥光源重大维修改造工程期间，开发的一套基于扫频激励法的工作点测量系统。测量系统硬件包括基于条带BPM的信号拾取电极、前端信号调理模块、一台带跟踪输出的信号分析仪N9000AEP、功率放大器以及用于激励束流的条带激励器。系统控制软件采用EPICS开发，基于EPICS Stream Device设计的输入输出控制器(soft IOC)运行在服务器虚拟机中，通过VXI11协议进行通信实现对信号分析仪的控制和数据获取；用户操作界面采用EPICS平台下的EDM开发，通过Channel Access与IOC通信。在HLS-II储存环上对工作点测量系统进行了在线的调试。调试结果说明，在扫频范围为2.1 MHz到4.1 MHz时，工作点测量系统的统计分辨率在水平方向上好于0.000 3，在垂直方向上好于0.000 2。Abstract: In the HLS-Ⅱstorage ring, a swept-frequency excitation(SFE) based tune measurement system has been developed and running well. This paper presents the construction and commissioning of the SFE-based tune measurement system. The system hardware includes spectrum analyzer with tracking, excitation module, strip-line kicker, signal processing module and beam position monitor(BPM) as signal pickup. The control software of the tune measurement system is developed using EPICS software. The control software consists of three parts: input/output controller, operation personal interface and channel access. The on-line test of the system is performed to investigate the system statistical resolutions in the two transverse directions. Test results reveal that the statistical resolutions are better than 0.0003/0.000 2 in the swept range from 2.1 MHz to 4.1 MHz.
