我们开发了一种新型的紧凑结构,称为耦合RFQ-SFER(CRS),加速0.8 MeV的氦束材料辐照项目。采用分离式射频四极杆结构代替射频四极杆的加速段,在单腔中实现了高的加速效率。在电磁模拟之后,执行CRS腔的RF测量,包括低RF功率和高RF功率测量。最近在CRS直线加速器上进行的束流实验表明,最大加速束流可达2 mA,能量为0.8MeV,能散(FWHM)为3.1%。实验测量结果与束流动力学模拟结果吻合较好。
We developed a novel compact structure, called a Coupled RFQ-SFRFQ (CRS), to accelerate a 0.8 MeV helium beam for a materials irradiation project. A high accelerating efficiency was achieved by replacing the accelerating section of the radio frequency quadrupole (RFQ) with a separated-function radio frequency quadrupole (SFRFQ) structure, in a single cavity. Following the electromagnetic simulations, RF measurement of the CRS cavity was performed, including low RF power and high RF power measurement. Recently, beam experiments on the CRS linac indicated that the maximum accelerated beam current could reach 2 mA with an energy of 0.8 MeV and energy spread (FWHM) of 3.1%. The experimental measurement results showed good consistency with the beam dynamics simulations.
