Abstract

THE SIMULATION OF ICRF HEATING EXPERIMENTS IN TOKAMAK PLASMAS IS DESCRIBED. THE MODEL TAKES INTO ACCOUNT FINITE LARMOR RADIUS EFFECTS AND KINETIC DAMPING IN FULLY TOROIDAL GEOMETRY. THE WAVE EQUATION FOR THE ELECTROMAGNETIC FIELD IS THEN A LINEAR PARTIAL INTEGRO-DIFFERENTIAL EQUATION. TO SEPARATE DISSIPATIVE TERMS FROM KINETIC FLUX TERMS IN THE POWER BALANCE ASSOCIATED WITH THE WAVE EQUATION IN A PLASMA WITH NON-VANISHING TEMPERATURES A NEW EXPRESSION FOR THE LOCAL POWER ABSORPTION IN ARBITRARY GEOMETRY IS DERIVED. A ONE-DIMENSIONAL CODE WHICH IS INTENDED TO BE INCORPORATED IN A RAY-TRACING PACKAGE TO MODEL THE BEHAVIOR IN THE VICINITY OF A RESONANT LAYER, IE MODE CONVERSION AND DISSIPATION, IS PRESENTED. THE MAIN PART OF THIS REPORT IS THE DESCRIPTION OF A GLOBAL CODE WHICH SOLVES THE WAVE EQUATION IN FULL TOKAMAK GEOMETRY. IT CAN SIMULATE MODE CONVERSION TO ION BERNSTEIN WAVES AS WELL AS ION CYCLOTRON DAMPING AT THE FUNDAMENTAL AND SECOND HARMONIC RESONANCE. ELECTRON MAGNETIC PUMPING AND LANDAU DAMPING HAVE ALSO BEEN INCLUDED.
