This paper reports on experimental and theoretical studies of a fundamental mode, large-orbit
gyrotron oscillator designed to produce high-power radiation in the rectangular TE,a mode at
about 650 MHz. A basic linear theory for design and operation is presented and experiments
confirm its applicability. Results of initial experiments have demonstrated 4Oh4.2 MW of
microwave radiation in pulses equivalent in duration to the electron beam, corresponding to an
efficiency of about 16%. In some cases, much greater power levels of lOO=l=20 MW were
observed at the expected frequency but in pulses of very short duration. In both cases, the
observed frequency and mode pattern were consistent with operation in the fundamental mode. Experiments also demonstrated that the observed radiation was linearly polarized, as expected.
