Abstract

A code was created to look into the stability of the spectrum launched by a new lower hybrid antenna used for heating and current drive of fusion plasmas, when the plasma loading conditions vary. The antenna is based on the passive-active multijunction (PAM), a concept promising greater immunity to conditions envisioned in the advanced scenarios for the International Thermonuclear Experimental Reactor (ITER). The code, requiring visualization of multidimensional data, is illustrated with applications to Tore Supra´s new antenna.
