【摘要】 为实现高频段高功率微波的相干功率合成,本文开展了自激振荡对X波段锁相相对论返波管振荡器工作特性影响的粒子模拟和实验研究,TM11模式的激励以及TE11模式在谐振腔之间的耦合是导致器件自激振荡的主要原因。在有效控制TM11模式激励的情况下,实验实现锁相RBWO的模式控制。更多还原

【Abstract】 To achieve high power microwave combining at high frequency band,an X-band phase-locked relativistic backward wave oscillator(RBWO) is proposed and investigated.The influences of the non-working mode oscillation on working characteristics of the phase-locked RBWO are explored in particle-in-cell(PIC) simulation and experiment.The experimental results agree well with the simulation,which indicates that the TM11’s excitation in the cavities and the TE11’s coupling between the cavities are the main cause of non-working mode self-oscillation.Finally,mode control of the phase-lockd RBWO is accomplished experimentally.更多还原
