Response of the COMPASS Plasma to Magnetic Perturbation Experiments

Popis výsledku v původním jazyce

It has been demonstrated on several tokamak devices that application of a Resonant Magnetic Perturbation (RMP) field on plasma can suppress or mitigate the Edge-Localized Mode (ELM) instabilities. One of the leading theories describes a reaction of the plasma to the RMP as an induction of screening currents on resonant surfaces. This manifests itself by generation of radial magnetic field, which can be measured in the experiment. In this work, magnetic diagnostics installed on the COMPASS tokamak are utilized to measure the RMP response field for two different RMP coil configurations. The measured plasma response field is compared to the original RMP field, as well as to the response field calculated by linear MHD code MARS-F. Consequently, the similarities and differences between the model and the experiment are discussed. Depth of penetration of resonant components (aligned with the pitch angle of magnetic fieldlines) of the RMP into plasma are calculated by the MARS-F code, and pres
