摘要
在ＢＥＳⅡ中顶点探测器代替了ＢＥＳ的中心漂移室，建立了相应的触发判选子系统。介绍了ＢＥＳⅡ顶点探测器触发判选子系统的原理、构成、逻辑设计和结果。该系统是北京谱仪触发判选系统升级改进的主要项目之一。
The vertex chamber is used instead of central drift chamber in BES Ⅱ. The vertex chamber trigger system of BES Ⅱ is introduced. This is one of upgradings of trigger system. The principle, constitution and logic of VC trigger are presented in this paper.
