Abstract

The design of a multifrequency tunable 1 MW, 10 s gyrotron (105-140 GHz) for controlling plasma instabilities in fusion Tokamaks is presented. It operates in the TE/sub 22,8/ mode at 140 GHz and the TE/sub 17,6/ mode at 105 GHz and some other modes in between. It is equipped with a magnetron injection gun (diode type), a cylindrical cavity, an advanced quasi-optical launcher, three specific beam forming mirrors and a CVD-diamond Brewster window.
