An analysis of quasi-optical grills for lower-hybrid waves for heating and current drive purposes is presented. The tokamak plasma density versus the abscissa entering the plasma is assumed to behave like a step and a subsequent ramp. The study is performed by means of a two-dimensional formulation employing cylindrical waves. A detailed numerical analysis is presented, which allows us to show results for different configurations useful in practical cases and comparisons with the constant-density case.

Abstract
An analysis of quasi-optical grills for lower-hybrid waves for heating and current drive purposes is presented. The tokamak plasma density versus the abscissa entering the plasma is assumed to behave like a step and a subsequent ramp. The study is performed by means of a two-dimensional formulation employing cylindrical waves. A detailed numerical analysis is presented, which allows us to show results for different configurations useful in practical cases and comparisons with the constant-density case.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
