我们的研究团队历时数年开发出一种混合单腔（HSC）直线加速器，其结构是将射频四极杆（RFQ）结构和漂移管（DT）结构组合成一个叉指H（IH）腔体[1]。在目前的工作中，分析了 HSC 直线加速器的几种不同结构，以实现最佳的腔电场分布并增强光束传输。所提出的 HSC 直线加速器设计是用于放射治疗的重离子同步加速器的直接注入直线加速器。该设计还具有作为硼中子捕获疗法中的中子源的潜力。根据我们的模拟，HSC 直线加速器在 1800mm 内将 C6+ 离子从 25keV/u 加速到 2MeV/u，在 100MHz 运行时提供 94kW 的馈电功率。本文报道了详细的 HSC 直线加速器结构设计和腔体电磁场仿真结果。
A hybrid single cavity (HSC) linac, whose structure is formed by combining a radio frequency quadrupole (RFQ) structure and a drift tube (DT) structure into one interdigital-H (IH) cavity, has been developed over a span of a few years by our research team [1]. In the present work, several different structures of an HSC linac are analyzed in order to achieve an optimum cavity electric field distribution and to enhance beam transmission. The proposed HSC linac design is a direct injector linac for a heavy ion synchrotron for radiotherapy. This design also has potential as a neutron source in boron neutron capture therapy. According to our simulations, an HSC linac accelerated C6+ions from 25keV/u up to 2MeV/u in 1800mm for a 94kW feeding power with a 100MHz operation. The detailed HSC linac structure design and the results of the cavity electromagnetic field simulation are reported in this paper.
