Conceptual Design of 20 kV RF Stacking Cavity

摘要: 分析了重离子束的射频堆积过程。在此基础上, 根据兰州重离子加速器冷却储存环 (HIRFL CSR)内束流流强为 10 12 ～ 10 14 s- 1的设计要求, 对用于束流射频堆积的高频腔体进行了物理设计。主要设计参数为 :腔体长度 1 9m, 铁氧体环尺寸2 0 0mm× 80mm× 2 5mm, 峰值电压 2 0 0kV, 频率范围 18 0～ 2 8 0MHz, 铁氧体中磁通量密度 10mT

Abstract: RF stacking process for heavy ions is analyzed in HIRFL cooler storage ring (HIRFL CSR). A RF cavity for heavy ions stacking is designed according to the requirement of the stacking processes. Its frequency range is 18.0～28.0 MHz and peak RF voltage is 20.0 kV. The other main parameters of the cavity are obtained by using transmission line theory and SUPERFISH code.
