Modeling of lower hybrid antennas using the ALOHA code and comparisons with Tore Supra experiments

A new code for lower hybrid antenna design and cold plasma wave coupling, named ALOHA, is presented. ALOHA takes into account the poloidal dimension of the antennas and the coupling to slow and fast waves. Comparisons with experimental data for the LH antennas installed on Tore Supra and the TOPLHA code show that ALOHA is a fast and efficient predictive tool.
