Abstract: Nuclear fusion in magnetic confinement devices is one of the most
challenging application fields for electromagnetics and mechanics. In
particular antennas, charged with the task of handling and delivering high
power to the plasma, have to operate in a harsh environment with very demanding
thermal and mechanical requirements. Within this scenario, the use of tools
able to efficiently predict the antenna behaviour is mandatory. In the present
work, the TOrino Polytechnic Ion Cyclotron Antenna (TOPICA) code has been used
to simulate the real 3D geometry of two launchers, generally operating at 30
MHz and presently installed on the ASDEX Upgrade tokamak. The working frequency
belongs to the Ion-Cyclotron range of frequencies that was proven to achieve
very efficient plasma heating. Antenna performances are presented in terms of
coupled power and RF potentials for different realistic plasma scenarios taken
from ASDEX Upgrade.
