Investigation of Improved Magnetron Characteristics with Transparent Cathode

ORAL

Abstract

In [1] we showed: (a) fast start and rate of build-up of oscillations, (b) magnetron operation in the stable 2pi mode over a wide range of magnetic field, and (c) very high output power levels ($\sim $ 1GW), when the transparent cathode was used. This work is an attempt to explain the reasons for improvement of the magnetron characteristics in terms of priming and/or the large amplitude of the azimuthal component of the RF electric field in the electron flow region. Different cathode designs were studied in computer simulations to investigate these two effects. \newline \newline [1] H. Bosman et al. IEEE Trans. Plasma Sci, 34 (4), 606 (2006).
