Abstract :
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.
