Spectroscopic Transport Studies at Stellarator Wendelstein 7-AS
By applying the technique of sinusoidal modulated blast to create a tracer, and a specially designed analytical procedure, this study examines size and parameter dependence of tracers in plasmas. The experiments are conducted at the Stellarator Wendelstein 7-AS. In parallel the traditionally applied methods for analysis of tracers and their results are compared to experiments utilizing the technique of gas oscillation. With the help of these experiments, the validity of neoclassical theory in describing a stellarator plasma is tested. This is of great importance in the case of the stellarator since it allows permanent operation. Hence, ways have to be found that enable the control and limitation of the concentration of tracers and the fusion output helium in quasistationary plasma discharges.
