摘　　要：在入口归一化均方根发射度为0.05mm·mrad时,北京大学1MeV射频四极场加速器ISR-1000束流传输效率为97%.当更换新的ECR源时发射度增加到0.2mm·mrad,此时束流传输效率下降为89%.在不改变腔体结构的前提下,对入口参数及极间电压进行了优化调整,将效率提高到98%.还进行了ISR-1000对入射束流参数的敏感性分析,给出了各参数允许的变化范围.ISR-1000 will be used as the injector of the SFRFQ, which is under development at Peking University. The possibility to improve its transmission has been investigated. In order to get better transmission, the input beam parameters and the vane voltage have been optimized without changing the structure of the RFQ. In addition, the error study on input beam parameters of ISRol000 has been carried out. The sensitivity of those parameters has been obtained by simulation.
