摘要: We explore the performance of a 12 stepped-cavity relativistic magnetron with axial extraction (12 RMDO) driven by an “F” transparent cathode (the is coaxial two azimuthal periods increased thickness and which looks like letter “F,” so we call it cathode) through particle-in-cell (PIC) simulations. It shown that using cathode, electronic efficiency 70% gigawatt output power obtained while reducing leakage current about 50% compared to usual cathode. Further PIC simulations demonstrate frequency bifurcation occurs mode switching can be achieved several hundred kilowatts input RF in RMDO For example, was found applied driver 180 kW for 10 ns, operating TE31 switched TE41 mode. also secondary electron ...
