Paper Abstract

The relativistic multiresonator magnetron is analyzed extensively in cylindrical geometry using the two-dimensional self-consistent particle-in-cell simulation code MAGIC. In particular detailed comparisons are made between the simulation results and the experiments by Palevsky and Bekefi [Phys. Fluids 22 986 (1979)] using the A6 magnetron configuration. Within a constant scale factor the computer simulations show a similar dependence of microwave power on magnetic field with dominant excitations in the ir and 2ir modes. In the preoscillation regime it is found that the electron flow in the simulations differs substantially from the ideal Brillouin flow model. In the nonlinear regime the gain is dominated by the formation of spokes. The effects of the power supply impedance on magnetron performance are also investigated. 1.
