Abstract

Results from megawatt gyrotron experiments operating between 110 and 140 GHz will be presented. The beam velocityspread has been measured using a retarding potential diagnostic. The measured perpendicular velocity spread was typicallybetween Ã‚Â±10% and Ã‚Â±15% for velocity ratios between 1.5 and 2.0. The spread was larger at higher beam currents. Goodagreement was also obtained between two separate measurements of the velocity ratio. A new experiment at 110 GHz is nowbeing assembled. This device will operate in the TE22,6,1 mode and will have an internal converter to produce a Gaussianoutput beam.
