Abstract :
Effective control of power absorption in tokamaks and stellarators could be achieved by the frequency tuning of ECH&CD power delivered by high-power gyrotrons. In this report some results of the development of a frequency tunable gyrotron with fused-silica Brewster window are presented. Excitation of several modes at 1 MW power level in the range of frequencies from 131 to 146.5 GHz is achieved. produced.
