| Abstract: | 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. |
