Recent modeling for the ITER ion cyclotron range of frequency antennas with the TOPICA code

Abstract This paper documents the analysis of ITER ion cyclotron resonance heating (ICRF) launcher using TOPICA code, throughout recent years’ design activities. The ability to simulate detailed geometry an ICRF antenna in front a realistic plasma and obtain input parameters, electric currents on conductors radiated field distribution next is significant importance evaluate predict overall system performances. Starting from reference geometry, we first investigated impact some geometrical numerical factors, such as Faraday Screen or mesh quality. Then final was object comprehensive analysis, varying working frequency, conditions poloidal toroidal phasings between feeding lines. performance has been documented terms power coupled fields. Eventually, four-port junction also included models.
