应用BAC法提高S波段5.5MW单注速调管效率

摘要

近年来,一种提高速调管效率的新方法——BAC法越来越受欢迎.北京真空电子技术研究所尝试采用BAC法来提高S波段5.5 MW单注速调管的效率,在维持管长不变的条件下,将原先45％效率提高到54％.下一步计划将BAC法应用到宽带多注速调管上.%A new BAC method for efficiency improvement of klystrons is more popular recently.It is used for an S-band 5.5 MW single-beam klystron in BVERI.An efficiency increasing from 45％ to 54％ is measured without any length modifying of the klystron.The BAC method is planned to be used in broad bandwidth multi-beam klystrons.
