PROSPECTS FOR HIGH-POWER QUASI-OPTICAL GYROTRONS OPERATING IN THE MILLIMETER-WAVE RANGE
The prospects for high-power (several megawatts) quasi-optical gyrotrons operating in the high frequency region (150 GHz and above) are considered. The analysis is mainly concerned with the physics of interaction between the annular electron beam and the electromagnetic field within the quasi-optical resonator, together with the constraints required by long pulse or CW operations. It is shown that powers of several megawatts at frequencies exceeding 150 GHz are possible if one can maintain single-mode operation in the overmoded quasi-optical resonators. A thorough performance study of the magnetron injection gun (MIG) for such high-power gyrotrons is also carried out using the adiabatic theory as well as numerical simulations.
