Abstract

The purpose of this research was to study the effect of the electric field profiles on the lower hybrid current drive efficiency during transient phases such as rampup. As a complement to the full ray-tracing/Fokker Planck studies, and for the purpose of optimisation studies, a simplified 1D model based on the adjoint Karney-Fisch numerical results has been developed. This report includes a description of the model and illustrates the method using numerical results obtained with the Tore Supra and NET/ITER parameters. An interpretation of the numerical results is also presented, together with a derivation of a simple and general scaling law for flux consumption.
