Location of the lower hybrid heating absorption zone in toroidal devices

Description

The location of the transformation of the incident electromagnetic wave into an electrostatic plasma wave near the lower hybrid resonance can be determined by using the ''warm'' plasma theory. This region corresponds roughly to the linear absorption region or to the source of non linear waves, since there the electric field is maximum. A numerical determination of this region is made for two toroidal devices: the WEGA stellarator and the JET Tokamak

Abstract (French)

La zone ou l'onde electromagnetique incidente se transforme en onde de plasma au voisinage de la resonance hybride inferieure peut etre determinee au moyen de l'equation de dispersion des ondes en plasma ''tiede''. Cette zone correspond approximativement a l'endroit ou se produit un amortissement lineaire ou, puisque le champ electrique y est maximum, a l'endroit ou naissent de nouvelles ondes par interaction non lineaire. Une application numerique determine cette zone dans deux machines toroidales: WEGA et JET
