作为清华大学紧凑型脉冲强子源(CPHS)工程RFQ加速器设计与加工的一部分，介绍了基切和偶极稳定棒的设计过程。特别是定量地描述了叶片间电压斜率与切边段局部频率之间的关系。在识别腔体中存在的模式的基础上，利用SuPerfish和MAFIA程序对具体参数进行了优化。此外，还简要讨论了偶极子稳定器棒的水冷要求。
As part of the design and machining of the RFQ accelerator in the Compact Pulsed Hadron Source (CPHS) project at Tsinghua University, the design process of the undercuts and dipole stabilizer rods is presented in this paper. In particular, the relationship between the inter-vane voltage slope and the local frequency of the undercut section is described quantitatively. With the identification of modes existing in the cavity, the specific parameters are optimized by the SUPERFISH and MAFIA codes. In addition, the water-cooling requirement of the dipole stabilizer rods is briefly discussed.
