A hybrid fluid-kinetic approach for 3D plasma edge transport in He-plasma at Wendelstein 7-X

摘要

Introduction The complex three-dimensional structure of the optimised stellarator Wendelstein 7-X can only partially be accessed by means of experimental measurements, as a consequence of the only quite limited number of measurements at distinct locations with different plasma crosssections and properties. This highlights the importance of precise modelling (i.e. numerical bookkeeping) as an extended method for understanding the three-dimensional nature.
