Abstract

The design of the lower hybrid launcher is configured to couple 1.5 MW of steady state lower hybrid heating/lower hybrid current drive (LHH/LHCD) power at 3.7 GHz to the Tokamak Physics Experiment (TPX) plasma. The launcher utilizes a unique laminated, water-cooled construction to achieve a compact array of 128 waveguides at the grille surface and includes real-time position control for plasma coupling. The design features of this launcher are described with details of the principal components and the possible upgrade of the launcher to 3 MW. Results of steady state thermal analysis of the launcher grille septa are included
