Description

The FTU (Frascati Tokamak Upgrade) 8 GHz Lower Hybrid system started operation with the first of its 9 gyrotrons. The 1 MW power output of the tube feeds a 12 x 4 waveguide grill obtaining, in routine operations, a net specific power higher than 10 kW/square centimeters. Good power coupling to the plasma is observed with reflection coefficients close to the theoretical expectations. Interaction of the launched waves with plasma electrons is detected up to a density of about 1020 m-3
