A semi-analytical model of RF condensation that can handle localized power depositions
Abstract
A nonlinear effect, RF (radio frequency) condensation, can be used to facilitate RF stabilization of magnetic islands. Previously studied semi-analytical models for RF condensation are suited mainly for broad deposition profiles and are unable to handle power depositions that are localized in the interior of a magnetic island. Here, a model is developed that can handle both localized profiles and broad profiles. This allows a comparison of RF condensation for narrow vs. broad deposition profiles, and it allows a study of the dependence of RF condensation of localized deposition profiles on key parameters.
