Abstract

Phase locking in driven relativistic magnetrons is demonstrated using 2D particle-in-cell simulations. It is found that injecting a driving signal prior to the onset of magnetron oscillations can decrease the locking time substantially from the characteristic time required to achieve phase locking by injecting the driving signal after the onset. Simulation indicates that magnetrons with small aspect ratio oscillate predominantly in the (pi) mode, while ones with large aspect ratio can oscillate in various modes which depend upon system parameters. Moreover, it is shown that the frequencies of magnetron oscillations decrease as the effects of nonlinear beam loading become more pronounced.
