Abstract

A 3D RAPLICASOL model is presented where simultaneous propagation and absorption of both the FW and the SW is achieved. The modelling conditions are relevant for experimental conditions in ASDEX Upgrade (AUG) tokamak, magnetic field of 2 T, gas mixture of 98.5% D + 1.5% H, ICRF (Ion Cyclotron Range of Frequencies) antenna frequency of 36.5 MHz, opposite phasing on the 2 straps and coupled power of 1 MW. A radial density profile from EMC3-Eirene simulations is used. The antenna geometry is simplified in the poloidal direction and the plasma parameters variations are taken into account only partially. In principle, the methods presented here are applicable to models with the full scale of complexity. Up to now, the SW propagation was avoided in simulations of the ICRF waves for tokamaks, usually by artificial density modification (vacuum layer) near the antenna strap. The importance of the SW as a source of electric fields and ICRF power deposition in the edge plasma is highlighted by this work.
