DISCRETE MONOTRON OSCILLATOR

We theoretically and numerically investigate the operation and behavio r of the discrete monotron oscillator, a novel high-power microwave so urce. The discrete monotron differs from conventional monotrons and tr ansit time oscillators by shielding the electron beam from the monotro n cavity's RF fields except at two distinct locations, This makes the discrete monotron act more like a klystron than a distributed travelin g wave device. As a result, the oscillator has higher efficiency and c an operate with higher beam powers than other single cavity oscillator s and has more stable operation without requiring a seed input signal than mildly relativistic, intense-beam klystron oscillators.
