采用多粒子跟踪程序BEAMPATH对53.667 MHz RFQ进行模拟计算，基于RFQ腔体冷测、机械测量的结果，在考虑其入口束流不稳定性、电压不平整度、高频系统稳定度、加工误差、安装误差等因素的情况下，对RFQ的出口束流品质和不稳定性进行了系统分析。结果表明，在现有的加工、安装水平下，提高RFQ入口束流稳定度和高频系统稳定度对束流在RFQ中的传输十分必要。

Based on the database from RFQ cavity cold model test and tip‐pole geometry measurement ,53.667 MHz RFQ was simulated by BEAMPATH code . The RFQ output beam quality and instability were analyzed as functions of input beam instability , voltage roughness ,stability of RF control system ,RFQ manufacturing error ,and mis‐alignment .According to these results ,it show s that it is essential for beam transmis‐sion in RFQ to improve input beam stability and RF control system stability at the pre‐sent level of machining and alignment .
