This talk will tackle the importance of keeping fusion machines “clean” before and during plasma operations. The typical sources of impurities and the effects of those impurities on plasma performance will be reviewed. We will introduce several wall conditioning techniques and discuss their suitability to different fusion devices. As an example, first results from the wall conditioning strategy deployed on the superconducting stellarator Wendelstein 7–X will be presented.
Presented by Andrei Goriaev (MSc, LPP-ERM/KMS and Ghent University, BE).
