RF Current Condensation via Top Launch ECCD for Island Stabilization

POSTER

Abstract

Radio frequency (RF) current drive can be used in tokamaks to reduce disruptions by stabilizing islands. In this project, we study the particular effects of plasma positioning and shaping on the RF current condensation by coupling the EFIT equilibrium solver to the OCCAMI code (Of Current Condensation Amid Magnetic Islands) and applying the resulting code to top launch electron cyclotron current drive (ECCD) stabilization of islands in DIII-D tokamak plasmas.
