Abstract :
Recently megawatt gyrotrons are found to suffer from parasitic oscillations induced by the electron beam prior to the desired interaction zone (the cavity). This paper describes experimental and theoretical investigations on both high and low frequency parasitic oscillations. A new measurement method is introduced to determine and characterize these undesired oscillations, and a dedicated experimental study is presented.
