Modeling of WEST plasmas with reduced Lower-Hybrid model: interplay with transport and parameter optimization

Abstract

International audienceA heuristic reduced model was developed in METIS [Artaud et al, 2018] for a fast and reliable Lower-Hybrid Heating and Current Drive (LHCD) power and current deposition. Its performance is studied in a stand-alone way through experiments and first-principle modeling comparisons within a WEST database. Its self-consistent evolution is then characterized through an integrated modeling approach incorporating the interplay with transport
