The gyrotrons developed at the University of Sydney are moderately-powered, broad- band, tunable sources of millimetre-submillimetre radiation. GYROTRON V has produced output at a wavelength less than 0.5 mm. The paper will describe the measurements on GYROTRON V including work which has employed a novel combination of a quasi-optical antenna with a blazed grating.
