BEPCⅡ注入器真空系统改造

Reform of the vacuum system for injector in BEPCⅡ project

注入器真空系统的改造由为各种微波功率源系统服务的真空系统和常规真空系统组成,根据实践工作中的着重点,详细介绍了注入器真空系统工作特点,并从原理及工艺上对各种新改造的子系统如电子枪真空系统、正电子源真空系统、速调管真空系统和常规真空系统给予说明,并简单介绍了BEPCⅡ注入器真空系统现在的工作状态。

The reform of the vacuum systems for the injector or a 200m-long linear accelerator in BEPC Ⅱ project comprises the vacuum system serving for various microwave power sources and conventional vacuum system. According to the key points found in practice, the operational characteristics of the vacuum system for the injector is described in detail, then some vacuum subsystems for electron gun, positron converter and high-power klystrons and the conventional vacuum system are also described separately in view of their operating principle and process technologies. The current working condition of the reformed injector is given.
