摘要
设计出工作于TM110模式的C波段腔式束流位置监测器,用MAFIA软件模拟谐振腔中的电磁场分布,并采用波导耦合的方法有效地解决了共模抑制问题,给出其仿真结果．计算了主要参数对于谐振腔频率的影响．并利用超外差原理设计出微波信号处理电路,最终转换成低频信号输出．
This paper presents the structural and electromagnetic design of a C-band cavity type beam position monitor, with working frequency of 5.712GHz. We use MAFIA to simulate electromagnetic field, the results show that the waveguide coupling scheme can reject the common mode TM010 effectively. Some major parameters which may affect TM110 frequency are calculated. A homodyne cicuit has been designed, which converts microwave signal to low-frequency output.
