Abstract: The gas stripper system of the EN tandem accelerator at the Peking University is being improved for AMS 10Be measurements with super high sensitivity. The design of a recirculation gas stripper, including the vacuum system and control system, is presented. The experimental results on a simulation test bench are also described.

Key words: recirculation gas stripper, accelerator mass spectrum (AMS), control, simulation experiments

摘要: 基于EN型串列静电加速器的北京大学加速器质谱系统(PKUAMS)将主要开展高灵敏度 10Be 测量,为此需要对该加速器的剥离系统进行改造。介绍了PKUAMS循环气体剥离器的研制,包括真空系统物理设计、模拟实验以及控制系统设计等。
