Abstract

During last years several new gyrotrons were developed at IAP/GYCOM. The main ITER requirements to a gyrotron have been demonstrated: 170 GHz frequency, 1MW power, 1000 seconds pulse duration, 53% efficiency. For a multi-frequency gyrotron a novel scheme for a tunable window was developed. Additionally some other new gyrotrons were developed for running plasma installations. New directions in the gyrotron development are studied: elaboration of gyrotrons at high frequencies (~300GHz) and investigation of the possibility to realize oscillations locking by means of external signal.
