HIGH POWER AND REPETITIVELY PULSED OPERATION OF A RELATIVISTIC EXTENDED-INTERACTION-CAVITY OSCILLATOR
An Oscillator of Relativistic Extended Interaction Cavity (REICO) is presented and manufactured successfully for the first time. The problems encountered with in the initial experiment are investigated, and the pillboxes and the triaxial output cavity of the REICO are optimized in this paper. The mode-competition of modulation was overcome by adjusting the gap width of pillboxes. The output microwave pulse width increasing from 20ns to 38ns and the repetition rates increasing from 15Hz to 100Hz are improved after optimizing the structures of the electron beams collection and the triaxial cavity. Using a 900kV, 16kA, 45ns electron beam, 4.1GW radiated power was extracted in 38ns FWHM pulses at 2.86GHz and 100pps. The power efficiency is 26％, and the energy efficiency is 22％. The average power is 16 kW.
