强流RFQ注入系统研制

Development of an injection system for a high intensity RFQ

本文介绍研制的强流RFQ注入系统。系统包括强流离子源、聚焦透镜、束流切割器等,注入系统在RFQ入口处形成了束流能量75keV、流强42mA、α参数为1.79、β参数为0.0596 mm/mrad、束流脉冲频率1-100 Hz、束流占空比1%-100%、发射度小于95.2πmm mrad的质子束,可满足强流RFQ对束流注入品质的要求。

An RFQ injection system consisting of an /on source, two focusing lenses and a beam chopper, etc. was developed The proton beam with parameters of α=1.79, β=0.0596 mm/mrad, repetition rate f=1-100Hz, beam duty factor D=1%-100%, emittance less than 95.2 p mm mrad, beam energy E=75keV, and beam current I=42 mA, can be produced to inject in to the RFQ.
