电荷剥离装置是串列加速器的重要组成部分。与固体剥离器和普通气体剥离器相比,循环气体剥离系统具有束流能散度增加少、等效剥离厚度高、束流接受度大和加速管内真空度高等优点。最近,为北京大学6MV串列加速器研制的循环剥离系统投入了使用,本文介绍该系统的基本结构、安装调试、束流实验以及由于加速器性能提高而得以开展的应用工作。 Charge stripping devices are important components of tandem accelerators. Compared with the solid stripper and the conventional gas stripper, the recycling gas stripping system has the advantages of less increase of beam energy dispersion, high equivalent stripping thickness, high beam acceptance, and high degree of vacuum in the accelerating tube. Recently, Peking University 6MV Tandem Accelerator developed cycle stripping system put into use, this article describes the basic structure of the system, installation and commissioning, beam experiments and due to the accelerator to improve performance and can be carried out by the application.
