Abstract
A high-power x-band coaxial relativistic backward wave oscillator has been conceptually designed and analyzed, The TMon dispersion relations in the coaxial corrugated cylindrical waveguide used in the device wa s calculated, MAGIC,an electronmagnetic particle-in-cell code, is bein g used to investigated the nonlinear beam-wave interaction and other d esign optimization issues, Preliminary simulation results shows that t he coaxial BWO can generate 2. 2 GW peak power microwave at 10. 15GHz in the TM02 mode driven by a 600-KV 20-KA electron beam,the peak power efficiency is about 18%.
