Investigation of a disc-loaded gyro-TWT using particle-in-cell simulation

Abstract

Beam-wave interaction behavior of a disc-loaded gyro-TWT amplifier has been investigated using PIC simulation with the help of a commercially available tool MAGIC.Here, a second-harmonic 91.4 GHz single-stage disc-loaded gyro-TWT operating in the TE02 mode has been simulated.Beam absent analysis has been presented for the device operation in the desired mode and frequency using eigenmode solver.Beam present analysis has also been demonstrated which yields an output power of 235kW at 91.4 GHz with input power 450W along with approximately 10% efficiency.
