高强度重离子加速器装置（HIAF）的建设。（2013）[1]在中国科学院近代物理研究所（IMP，CAS），最近在中国广东省惠州市开始。HIAF的设备之一是光谱仪环（SRing）。SRing设计有两个磁性合金（MA）加载腔，用于将重离子束（例如238 U+ 92束从800 MeV/u减速到30 MeV/u）减速，SRing将作为多功能实验储存环。MA腔设计工作在1.006-0.503 MHz的频率范围内，最大电压为50 kV，峰值功率为220 kW。本研究描述了可变谐波RF减速腔的设计和中国MA堆芯的性能测试。
The construction of the high-intensity heavy-ion accelerator facility (HIAF) Yang et al.(2013)[1] at the Institute of Modern Physics, Chinese Academy of Science (IMP, CAS), has begun recently in Huizhou, Guangdong province, China. One of the devices of the HIAF is the Spectrometer Ring (SRing). Designed with two magnetic alloy (MA) loaded cavities to decelerate the heavy-ion beams, such as a 238 U+ 92 beam from 800 to 30 MeV/u, the SRing will serve as a multi-functional experimental storage ring. The MA cavity design works in the frequency range of 1.006-0.503 MHz with a maximum voltage of 50 kV and peak power of 220 kW. This study describes the variable-harmonic RF deceleration cavity design and a performance test of Chinese MA cores.
