Impurity Dynamics in Turbulent Plasma in Tokamak Scrape-off Layer

Publication at Faculty of Mathematics and Physics |
2010

Abstract

We simulate behavior of impurities in turbulent potential in tokamak scrape-off layer. Assuming low density of impurities we use test particle approach to investigate movement of individual particles in time evolving potential of isolated structure generated by interchange instability.

Behavior of the plasma is modeled using reduced fluid model ESEL.
