Project Details


The project is devoted to theoretical studies and numerical modelling of the interaction of externally produced nonaxisymmetric low frequency magnetic field perturbations with
tokamak plasmas. Such perturbations are produced eighther on purpose (erdogic divertors, dynamic ergodic divertors, use of MHD control coils for ELM mitigation) or non-intendedly (error fields in tokamaks).
The kinetic approach to this problem which has been already developed for a simplified tokamak geometry ignoring toroidal effects and using a simplified collision model should be generalized to realistic tokamak geometries and collision models. The kinetic model will be used to study the penetration of magnetic field perturbations and the generation of plasma rotation in Dynamic Ergodic Divertor experiments at TEXTOR (Forschungszentrum Juelich) and also to study Edge Localized Mode control in experiments at DIII-D (National Fusion Facility San Diego).
The results should help to interpret and plan future experiments and also should be used in transport modelling at DIII-D with the help of the 3D Monte Carlo edge code E3D.
