文摘The preliminary design results of a 1-MW,Kuband gyrotron traveling wave amplifier(gyro-TWA)are presented.Operating at the second cyclotron harmonic of the TE11 mode,the amplifier characterizes good stability even in the case of no distributed losses loaded,which could potentially allow it to be operated at high average power.Large signal simulation shows that the amplifier can generate a saturated peak power of about 1MW with efficiency of 26.6%,gain of 31 dB,and 3-dB bandwidth of about 1 GHz when driven by a 100 kV,40 A electron beam with 5%axial velocity spread.
