Abstract In the design of a 120 GHz 200 kW quasi-optical gyrotron, we have analyzed the influence of the open resonator geometry (two circular mirrors facing one another) on the electronic efficiency, the ohmic losses, the output coupling and the multimode behavior. The method we have used to optimized the resonator design will be presented. Mode selectivity is improved by using a resonator formed by two mirrors each of which has a central step. Numerical simulations show that single mode operation can also be attained in the more favorable situation of a magnetic field having a positive taper over the interaction region.
