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
本文系統的介紹了速調管的工作原理、主要特點、發展概況、主要性能指標和技術特點，解析的研究了電子束在相對論速調管放大器的調制腔和漂移管中的預群聚;用粒子波互作用的場方法導出了在輻射腔中預群聚電子束產生輻射的自洽方程，同時對線性區的增益進行了計算。理論分析表明，場分析法可用於計算單注單間隙、多注多間隙、單注多間隙和多注多間隙速調管輸出迴路的諧振頻率、間隙阻抗實部和外觀品質因數等特性參數。The virtual cathode oscillator ( vircator ) is one of the most important devices that can produce high power microwaves. for the increasing of microwave power and the locking of operation frequency, researchers have proposed many different types of improved vircators
軸向反饋式虛陰極振蕩器主要利用反饋微波調制電子束和虛陰極，從而增大微波輸出功率、提高效率、穩定頻率、凈化模式。The wakefield excited by an ultrashort and ultrahigh laser pulse propagating through tenuous plasma can accelerate electrons to extreme high energy. this can be used as a mechanism to design minitype electron accelerator. this thesis is devoted to studying those issues relevant to the wakefield accelerator, namely the laser wakefield accelerator ( lwfa ), laser wakefield accelerator driven by multiple pulses ( mp - lwfa ), plasma beat wave accel - erator ( pbwa ) and self - modulated laser wakefield accelerator ( sm - lwfa )
