摘　　要：西安200 MeV质子应用装置(XiPAF)主要用于空间辐照效应模拟研究,为了满足实验需求,XiPAF采用三阶共振慢引出的方式引出束流。本文首先分析了影响XiPAF慢引出效率的因素,针对共振六极铁(SR)上升引起直流电流传感器(DCCT)束流强度变化及RF-KO阶段引出效率进行了优化。优化后,RF-KO阶段引出效率最高能达到89%,总引出效率最高为84%。Xi’an 200 MeV Proton Application Facility(XiPAF)is mainly used for the simulation of space irradiation effect.To meet the experimental requirements,XiPAF uses the third-order resonance slow extraction method to extract the beam.Firstly,this paper analyzes the factors affecting the slow extraction efficiency of XiPAF,and then optimizes the beam intensity change of DC current sensor(DCCT)caused by the rise of sextupole resonance(SR)and the extraction efficiency in RF-KO stage.After optimization,the maximum extraction efficiency of the RF-KO stage can reach 89%,and the maximum total extraction efficiency is up to 84%.
