北京大学在20世纪90年代末成功研制了1台整体分离环重离子射频四极场(RFQ)加速器ISR-1000,近年来经升级后它可提供1 MeV/2 mA氧离子束流。为提高RFQ加速器在较高能量下的加速效率,北京大学提出并正在研制1种新型分离作用RFQ加速结构(SFRFQ),所建造的加速腔实验样机可与ISR-1000构成组合加速系统,将mA级氧离子加速到1.6 MeV。北京大学参与了“973”项目350 MHz四翼型强流质子RFQ加速器的研究,并研制了1台全尺寸无氧铜工艺腔。北京大学还计划在近年内建造1台中子源用201.5 MHz2、MeV/50 mA微翼四杆型氘离子RFQ加速器。
Peking University successfully developed the ISR-1000, an integral split-ring radio-frequency quadrupole field (RFQ) accelerator in the late 1990s that has been upgraded to provide 1 MeV / 2 mA oxygen ion beam in recent years. In order to improve the accelerating efficiency of RFQ accelerator under higher energy, Peking University proposes and is developing a new type of separation RFQ acceleration structure (SFRFQ). The accelerated cavity experimental prototype can be combined with the ISR-1000 to accelerate the system. The mA Stage oxygen ions accelerated to 1.6 MeV. Peking University participated in the “973 ” project 350 MHz quadrupole strong proton RFQ accelerator research and developed a full-size oxygen-free copper process chamber. Peking University is also planning to build a 201.5 MHz2, MeV / 50 mA four-pole deuterium ion RFQ accelerator for its neutron source in recent years.
