Abstract

The use of Resonant Magnetic Perturbation (RMP) coils is as an experimental technique for mitigating or suppressing large Edge Localized Modes (ELMs) in a number of tokamaks. In this work, we introduce a newly developed extension of the EBdyna_go code (introduced in [1]) that was designed to resolve the full-orbit of charged particles, in a collisionless manner. The new version of the code allows to study motions in the 3D perturbed fields generated by RMPs. This field can be calculated by a Biot-Savart solver or an integrated MHD code such as MARS-F [4]. The model has been applied on the COMPASS tokamak, comparing it with its RMP
experimental database [2]. In particular we have focused here in the modelling of a High-Field-Side (HFS) RMP experiment with a dominant n=2 toroidal mode number.
