Abstract

Preliminary ECW experiments on TEXTOR have been performed using a 110 GHz, /spl sim/350 kW, 200 ms, gyrotron. This system has been operating reliably since beginning in 2000. The system is now being upgraded to up to 1 MW, 10 s at 140 GHz. while operation of the old 110 GHz gyrotron will remain possible mainly for diagnostic purposes. The two gyrotrons will have their own beam forming and polariser units but the main part of the quasi optical transmission line will be used both for transmission of the 140 and the 110 GHz power, including window and launcher.
