Paper Abstract

Experimental results of the first operation of a quasi-optical gyrotron on the second harmonic are presented. With a large (mirror separation d = 329mm) unoptimized Fabry-Pérot resonator (ohmic losses = diffractive losses), a nearly monomode emission (ƒRF≃197GHz) at a power level of 8kW has been measured for a beam current of 3A (Vb = 78kV). Numerical simulations show that operation at the second harmonic is highly sensitive to velocity spread.
