An inverted magnetron, with its cathode on the outside and anode on the inside, exhibits faster startup than a conventional magnetron because of the negative-mass behavior of the rotating electron. The tendency toward azimuthal bunching in rotating electrons in a crossed-field device is analyzed with the Particle-In-Cell code, MAGIC.
Using a hybrid approach, 3-D simulations of magnetic priming of a relativistic magnetron have been performed. The primed magnetic field values were calculated using a magnetostatics code (Magnum) and then imported into a particle-in-cell code (Magic PIC) and run for the case of a six-vane relativistic magnetron. The magnetically perturbative structures chosen for implementation in these simulations...
