分离功能 RFQ (SFRFQ) 被提出作为 RFQ 的后加速器，用于在低频下加速重离子。它在四极电极中引入了间隙加速，因此比传统的RFQ加速器具有更高的加速效率。第一个 SFRFQ 原型腔经过专门设计和构建，作为后加速器，可将 O+ 束流从 1.03 MeV 加速到 1.64 MeV。在完成低功率测量和高功率测试的基础上，进行了波束调试，验证了其可行性。实测SFRFQ的单电池能量增益为45 keV，比北大整体裂环（ISR）RFQ高约60%。
Separated Function RFQ (SFRFQ) was proposed as a post accelerator of RFQ to accelerate heavy ions at low frequency. It introduces gap accelerating in the quadrupole electrodes, and therefore it has higher accelerating efficiency than the conventional RFQ accelerator. The first SFRFQ prototype cavity has been specially designed and constructed as a post accelerator to accelerate O+ beam from 1.03 MeV to 1.64 MeV. Based on accomplishment of low power measurement and high power test, the beam commissioning was carried out to verify its feasibility. The measured energy gain per cell of SFRFQ is 45 keV, which is about 60% higher than that of Peking University Integral Split Ring (ISR) RFQ.
