Space charge wave revision to the electron beam bunching caused by the radiation wave in the klystron
在速調管中空間電荷波對輻射波引起的電子束群聚的修正The basic principle, main properties, typical parameters, technical characteristics and general situation of klystron are introduced. the electron beam prebunching in the modulated cavity and shift tube of relativistic klystron amplifer ( rka ) is studied analytically, a self - consistent equation of radiation generated by the prebunched electron beam in the radiation cavity is derived using the field method of particle ? wave interaction instead of the electrical circuit method, and in terms of it, the gain in the linear regime calculated, a field analysis method is proposed. the theory analysis shows that the characteristic parameters, such as resonance frequency, real part of gap - impedance, external quality fadtor in all kinds of klystron output circuits including single - beam, multi - beam, single - gap, multi - gap, single - beammulti - gap, multi - beam multi - gap klystron output circuit, can be calculated by the field analysis method
