延时注入对驻波加速管X线输出量的影响

THE INFLUENCES OF THE DELAY INJECTION ON THE X-RAY OUTPUT OF THE STANDING WAVE ACCELERATING TUBES

摘要: <正> 一、引言驻波加速管工作于脉冲方式时,在每个微波脉冲的开始和结束时,加速管内场强有一个建成和衰减的过渡过程,在过渡过程中,加速场强随时间不断变化,如果电子束和微波功率同时注入及馈入驻波加速管,则将有较多的低能电子产生,它们不仅增加加速管的负载,使输出能谱变坏,而且这部份低能电子对X线输出量的贡献也不大。由于过渡过程的

Abstract: In the paper, the influences of the delay injection of the electron gun beamson the X-ray output of the standing Wave accelerating tubes are analyzed theo-retically. The experimental results are compared with the theoretical analysis.
