摘　　要：北京正负电子对撞机升级改造工程BEPCⅡ的重要组成部分——直线加速器于2006年7月通过了所内预验收,其中定时系统是全新建造的基于EVG/EVR的事件定时系统,于2006年3月起投入运行,为直线加速器的电子枪、微波激励源、能量倍增器、正电子源、调制器、BPM等设备提供精确的时序触发信号。本文介绍直线加速器定时系统的研制、安装调试、运行和改进等工作情况。BEPCII is an upgrade project of the Beijing Electron Positron Collider （BEPC）, of which the injection linac has been upgraded to increase its beam current and energy, and to improve the machine stability as well. As an important part of the BEPCII Linac, a new timing system, based on event generator and event receivers, has been established and working smoothly since March of 2006 to provide the preelse synchronizing triggers to the electron gun, the RF system, the positron source, the klystron modulators and beam position monitors. In this paper, more details about the system will be presented, including its development, construction, commissioning and operation.
