Carbon and oxygen have been identified as the two major impurities in the first limiter operational phase of the stellarator Wendelstein 7-X. We evaluate basic differences between these impurities regarding the effective charge state in the boundary region of the plasma utilizing a computational approach. The method applied here is based on the previous work [1] and extends it to two ... https://herbsdailyes.shop/product-category/mouthwash-and-gargle/
