Experimental demonstration of relativistic magnetron with modified output configuration

Abstract

A modified configuration of relativistic magnetron with diffraction output has been investigated experimentally by using repetitive pulsed power generator “ETIGO-IV” (400kV, 13kA, 120ns, 1Hz). The purpose is to verify the improved microwave conversion efficiency predicted by numerical simulations [M. Daimon and W. Jiang, Appl. Phys. Lett. 91, 191503 (2007)]. The experiments have concentrated on comparison between the output microwave powers obtained by using the modified and the conventional configurations of relativistic magnetron. The results have been in general agreement with that obtained by the simulations.
