Study of Output Performance of Partially Dielectric Loaded A6 Relativistic Magnetron

A three dimensional particle-in-cell code MAGIC-3D is used to examine the output performance of a partially dielectric loaded A6 relativistic magnetron. The side resonators of the resonant structure are loaded symmetrically at angle of 120 with low-loss dielectric material. The simulation of dielectric loaded A6 relativistic magnetron is performed for -mode of operation. The formation of six electron spokes in the oscillation region confirms -mode oscillation of a six vane relativistic magnetron. The results indicate single -mode operation with improved radiated output power of 620 MW with relatively low start-up time in comparison to unfilled resonant structure. A power increase of 40% is found in case of partially filled dielectric resonator in comparison to unfilled dielectric resonators.
