Abstract
The simulated behavior of a 100-GHz reentrant linear magnetron operated at a beam voltage of 2 kV is investigated using a two-dimensional particle-in-cell MAGIC code. The dimensions of the ten-vane reentrant resonator are selected to give a -mode resonance at 100 GHz, showing mode separation with the adjacent -1 mode of 0.2 %. The electron distribution and the time variation of the electric energy in each vane reveal that the -mode oscillation is dominant when the injected current density is several times higher than the start oscillation current, although the -1 mode is excited near the start oscillation current. With variation of the injected current density from 40 A/cm2 to 60 A/cm2, the generated power density is increased from 0.32 W/mm2 to 0.54 W/mm2 for an external magnetic eld of 0.78 T.
