Abstract
Recently, an internal mode converter system has been installed in a 1.5 MW, 110 GHz gyrotron at MIT. We achieved an output power of 1.5 MW, corresponding to an efficiency of 37 % at a beam voltage of 96.6 kV and a beam current of 42 A. A Gaussian output beam was measured and the beam waist was determined. The depressed collector has been also setup. With a depressed collector, the efficiency was 50 % at an output power of 1.5 MW with a depressed voltage of 25 kV
