Self-consistent simulation of harmonic gyrotron and peniotron oscillators operating in a magnetron-type cavity

A self-consistent, large-signal computer simulation code is developed to study the interaction between the RF wave and a large helical-orbit. axis-encircling electron beam in a magnetron-type open cavity. The theory and the results of simulations of different modes of oscillations operating in an eight-vane cavity are given and discussed. A novel type of peniotron interaction that gives high efficiency for realistic thick beams is revealed.<
