事件系统在SSRF主定时系统中的应用

Application of event system in SSRF timing system

介绍一种全新概念的定时系统——事件系统在SSRF主定时系统中的应用。该事件系统以广播的形式将定时信息全局地分布到所有加速器部件,能完成所有SSRF主定时系统要求,具有网络结构清晰、简单、性价比高、技术先进、隔离性好、扩展和升级容易等优点。本文侧重介绍如何用事件系统的内部功能实现SSRF主定时的基本任务。测试结果表明主电压与500MHzRF时钟之间的同步晃动为31.44ps。

An event system distributes all timing signals to all parts of accelerator by way of broadcast. It can satisfy all requests of SSRF main timing system with clear network, high cost effectiveness, advanced technology, good isolation, easy update and expandability. In the paper, it is introduced how to complete the basic tasks of SSRF main timing system with the event system. The test proved that the jitter between main voltage and 500 MHz RF source was 31.44 ps.
