Design and PIC Simulation of a Millimeter Wave Gyro-twystron Amplifier
In this paper, a millimeter wave multi-cavity gyro-twystron has been designed and studied for beam-wave interaction behavior using a finite integration (FI) based 3D particle-in-cell (PIC) code. The PIC simulation of the current gyro-twystron predicted a maximum RF output power of ∼214 kW in TE01 mode at 35 GHz for 70 kV and 9.2A helical electron beam. The gain and bandwidth were calculated as ∼53 dB and 1.5 GHz, respectively. The efficiency of the amplifier was calculated as ∼33 %. Further, the present simulation results were validated with a nonlinear theory.
