Abstract: [eng] [cze]
(Hamiltonian chaos and its application to anomalous dynamics in turbulent environment) RMP-induced ELM control has been tested on several tokamaks. It is believed that increase of electron transport across the magnetic field plays an important role. Edge plasma turbulence also affects dynamics in the edge region of tokamak. We study the simultaneous effect of plasma turbulence and RMP-induced stochastic magnetic field within the single-particle framework. We find out that the plasma turbulence is an important element of dynamics that should be taken into account in further (especially single-particle) studies. Hamiltonovský chaos a jeho aplikace na anomální jevy v turbulentním prostředí Utlmenie ELMov využitím RMP bolo experimentálne odskúšané na viacerých tokamakoch. Predpokladá sa, že za efektom tejto metódy je nárast transportu elektrónov naprieč magnetickými siločiarami. Dynamika na okraji tokamaku je tiež ovplyvnená turbulenciou. Skúmame súčasný efekt turbulencie v plazme a efekt stochastických siločiar na dynamiku častíc v rámci jednočasticového priblíženia. Zistili sme, že plazmatická turbulencia má na dynamiku častíc značný vplyv, a to ako pre elektróny, tak aj pre ióny. Turbulencia by preto mala byť zahrnutá do budúcich, hlavne jednočasticových, modelov.
