Investigation Of The Operating Characteristics Of A 12-Cavity Rising-Sun Relativistic Magnetron With Diffraction Output Using Particle-In-Cell Simulations

We report on the performance of a 12-cavity rising-sun relativistic magnetron with diffraction output (12-cavity rising-sun RMDO). Particle-in-cell simulations show an electronic efficiency of 70% for a gigawatt output power 12-cavity rising-sun RMDO with a transparent cathode operating in the pi mode for an applied voltage of U similar to 400 kV +/- 50 kV. When the RMDO is driven by the "F" transparent cathode, which is a coaxial transparent cathode, the axial leakage current can be reduced by about 50%. Published by AIP Publishing.
