Title: Comparison of top and side launch of lower hybrid waves in the PLT tokamak

Abstract

For identical 90/sup 0/ settings the side coupler of the PLT 2.45 GHz, 1 MW lower hybrid system is more efficient at driving current than the top coupler at densities between 1 and 2 x 10/sup 13/ cm/sup -3/. We interpret this to be a reflection of the toroidal n/sub parallel/ upshift introduced by top launch. Measurements with 90/sup 0//60/sup 0/ (side/top) phase setting produces identical ..delta..I, as predicted theoretically from the ray tracing code.
