The mode competition and amplitude instability of Relativistic Extended Interaction Cavity Oscillator encountered with in the initial experiment were investigated in this paper.The modulation mode-competition was overcome by adjusting the modulation cavity gap width.The pulse repetition rates increasing from 15Hz to 100Hz and the output microwave pulse width increasing from 20ns to 38ns were improved after optimizing the structures of the electron beams collection and the triaxial output cavity.Using a 900kV
16kA
45ns electron beam
4.1GW radiated power was extracted in 38ns FWHM pulses at 2.85GHz and 100pps.The power efficiency is 26%
and the energy efficiency is 22%. The radiated average power is 16kW.
