Abstract
An electromagnetic particle-in-cell code has been used to simulate the nonlinear beam wave interaction and other optimization issues of a X-band RBWO with variable couple impedance, the simulation results show: the device can high-efficiently generate microwave radiation of 950MW peak power at (9.06±O.03) GHz when it is driven by a 5KA-500KV annular electron beam, peak power efficiency is 38%. The preliminary experiment results show that the microwave-generating efficiency of the non-uniform impedance RBWO is about twice of the uniform case in the same operating conditions.
