摘　　要：简单介绍了北京大学在高频四极场（ＲＦＱ）加速器方面的研究情况和取得的成果，包括束流动力学研究、ＲＦＱ腔的高频特性及工艺加工可行性等．现已研制成功一台２６ＭＨｚ整体分离环型ＲＦＱ加速器，其极间电压达８２ｋＶ，把Ｎ＋离子从２０ｋｅＶ加速到３００ｋｅＶ．The advances and achievements of studies on an integral split ring (ISR) RFQ accelerator for heavy ions at Peking University are presented in this paper.These include beam dynamics of RFQ accelerator,RF characteristics of RFQ cavity and studies of technological design.A 26MHz Prototype ISR RFQ resonator has been built .The voltage of 82kV between the electrodes and the acceleration of N + beam from 20keV to 300 keV have been achieved.These have proed the feasibility and advantage of this type of RFQ accelerator.
