Abstract

Abstract

A new type high efficiency Multiwave Cerenkov Generator is designed by employing a resonant cavity between the second slow wave structure and the output horn，and its physical process is analyzed by means of 2.5 PIC simulation. It is shown that, due to the decelerating gap mechanism and coupling cavity mechanism of the resonant cavity, its output power and efficiency increase as its longitudinal length reduces and its guiding magnetic field be lowered greatly. A typical simulation result is that, at the magnetic field of 0.63T, an Xband microwave with the average output power of 1.8GW and the peak power of 4GW is obtained with the input power of 5.8GW, and the average efficiency is over 30%.
