Abstract

Abstract: A coaxial compact L-band coaxial relativistic backward wave oscillator is investigated using the 2.5 D particle simulation code. Detailed physical interaction pictures of the oscillator are presented. Simulation results show that for an electron beam of 700keV and 10kA, a microwave of coaxial TM₀₁ mode is generated with power of 2.2GW and frequency of 1.60GHz when the external guiding magnetic field is about 0.9T. The beam to microwave efficiency is about 30％. The optimized electromagnetic structure of the device is only 100mm×520mm.

Key words: high power microwave, coaxial BWO, L-band, particle simulation
