NUMERICAL SIMULATION OF LOWER HYBRID HEATING AND CURRENT DRIVE IN TOKAMAKS
A model based on electron quasi linear Landau damping or non linear absorption theory, ion stochastic heating and including toroidal propagation effects was developed. It takes into account RF modified electric conductivity or electron heat transfer, RF induced impurity and/or cold neutral release and the presence of light gas minority or gas mixture. Confinement of the fast ion tail is investigated and the corresponding losses evaluated. This model is coupled to a 1-D radial transport code. Simulation of Petula results on heating and current drive or ramp up was made with the aim to calibrate the code. The various aspects of these simulations and corresponding fitting are described in detail in this report, as well as a prospective application to current ramp up in INTOR.
