Abstract :
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).
