Abstract
The propagation and absorption structures of ICRF (ion cyclotron range of frequencies) waves in the INTOR Tokamak plasma are investigated. The kinetic wave equation is solved for a deuterium-tritium plasma by employing a one-dimensional model equilibrium of the tokamak plasma. The wave is assumed to be excited by the poloidal antenna current in the low-field side. The accessibility of the ICRF wave, its energy deposition profile, the partition of absorbed energy between plasma species, and the antenna-plasma coupling are studied. The dependence of the energy absorption rate on the plasma parameters and the antenna location are examined.
