摘要
介绍了北京大学104mhz射频四极子加速器的电气模型,并在此基础上对各关键几何参数进行了仔细的扫描和选择,以提高射频四极子加速器的内在品质因子和分流阻抗等射频特性,从而降低射频四极子加速器的功耗。此外,还对电极间电压的平整度调谐进行了原理研究。此外,还设计了一个磁耦合回路,用于从发射机馈电RFQ腔。利用三维电磁场程序CST Microwave Studio (MWS)进行了相关的数值模拟。
Simulation Study on 104 MHz Radio Frequency Quadrupole Accelerator
An electrical model of the 104 MHz radio frequency quadrupole (RFQ) accelerator at Peking University is introduced for RF design, based on which every crucial geometrical parameter is swept and selected carefully to improve the RF properties of the RFQ such as the intrinsic quality factor and shunt impedance for reducing its power consumption. Moreover, flatness tuning of the inter-electrodes voltage is investigated in principle. Also, a magnetic coupling loop is designed for power feeding of the RFQ cavity from transmitter. Relevant numerical simulations are performed using 3D electromagnetic field program CST Microwave Studio (MWS).
