Abstract :
High power cw gyrotrons operate with an RF-power of up to 1 MW and efficiencies of 35-60 %. The waste power remains in the spent electron-beam and must be dissipated in the gyrotron-collector. Such collectors have strong sophisticated water-cooling systems for continuous operation. The electron-beam strike area on the collector surface is moved between an upper and a lower turning point by sweeping magnet fields in order to achieve a smooth power deposition.
