WitrynaAn impurity is something that ruins the uncontaminated nature of something. If someone accuses you of impurity, they think you or your nature has been spoiled in some way … WitrynaThe impurities injected into the W7 -X plasma during OP1.2b of W7- X are Al, Si, Ti, V, Mn, Fe, Ni, Cu, Mo and W. Sometimes multi- impurities (e.g., V, Mn and Ni) are …

In contrast to pre-divertor limiter operation, the island divertor in W7-AS enabled plasma density control even in the presence of a strong NBI-source, showing a significant ... 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 W7-AS- and International Stellarator Scaling (ISS95) (Fig.1). The profile change can nicely be demonstrated in a 1MW discharge close to the density threshold where the transition occurs within the pulse duration (Fig.2). The lowest impurity confinement times were observed when WitrynaOne prominent method to study the impurity confinement in W7-X is based on dedicated injection of impurity ions via the laser blow-off technique [2]. This method was applied in 123 experimental programs with different plasma parameters and magnetic field configurations. The evaluation of the injection by means of the already established …
