Abstract:We describe the results of a multi-scale, multi-physics modeling assessment of SOLPS-ITER, hPIC2, RustBCA and Xolotl, in which five single-crystal tungsten (W) samples were placed in a reciprocating collector probe and exposed to helium (He) plasma in the WEST fusion device. In our models, we considered a pure (100 %) He plasma, as well as one with oxygen (O) present (95 % He 5 % O) corresponding to the impurity concentration estimated during the C4 He campaign in WEST. Our SOLPS simulations approximately matc… Show more
