Witrynaof W7-X, the simulations predict a dominant role of the perpendicular transport across the island O-point along the ‘upstream’ f ow stagnation zone [15]. This leads to a variation of the impurity retention based on the source location, which will now be tested in the upcoming campaign of W7-X.

WitrynaThe knowledge of the impurity content and transport behaviour in fusion plasmas is crucial for reactor operation due to impurities restricting the operational parameter space of a fusion reactor. The Wendelstein 7-X stellarator (W7-X) is the most recent experiment in the steady state capable stellarator fusion reactor Witryna1 gru 1992 · In order to study the impurity production, transport and deposition on W7-AS a retractable collector probe, spatially distributed long term samples (LTS) and a thermal Li beam have been applied. Surface analysis of the LTS shows strongly enhanced impurity fluxes to restricted regions of the wall. Using the retractable … first person shooter games free steam
