Analysis of the Gyro-Back Wave Oscillations of the TE21 Mode
TE21模回旋返波振荡的起振分析

Based on the linear theory of gyro-TWA,this paper is focused on the numerical simulations for the relations of the starting length and starting frequency with beam radius,voltage,velocity ratio,beam current and magnetic field for a gyro-BWO operating in the TE 21 mode at fundamental or second harmonic and the corresponding physical mechanisms is explained.And the effect of distributed wall losses on the suppression of the TE 21 mode gyro-BWO is discussed.The results in this paper are helpful for the design ...
