| 摘 要： | 一台201.5MHz、2MeV、50mA的氘离子射频四极场（RFQ）加速器将用于北京大学中子实验平台。该加速器用4杆型谐振结构，同时为方便水冷采用了微翼型电极。射频结构设计使用了三维电磁场模拟软件Microwave Studio®，并力求满足降低二极场效应和射频功率损耗的要求。文章讨论了优化设计方法并给出一个设计结果。

| Abstract: | A 201.5 MHz,2.0 MeV,50 mA deuteron Radio Frequency Quadrupole (RFQ) accelerator is proposed as the neutron generator for the Peking University (PKU) Neutron Experiment Facility. For the good performance at the frequency ～200 MHz,the 4-rod resonator structure is chosen. Also,the mini-vane-type electrode is adopted for convenient water-cooling. The total RF structure design studies are performed by one of the most reliable 3D electromagnetic field simulation software,CST Microwave Studio(○R),with attentions to meet the demands of lowest dipole effect as well as minimum RF power consumption. The detail optimization methods and results are presented. |
