Multiscale modeling of BeD release and transport in PISCES-B

Observation of BeD sputtering in several different fusion plasma devices demonstrates the need to include these molecules into predictive modeling codes. In this work, Molecular Dynamics simulations are used to obtain information about sputtered BeD molecules and the results are implemented into the plasma impurity modeling code ERO. Rates for dissociation and ionization of BeD molecules in the plasma are also estimated. The modeling results are compared with PISCES-B experimental spectroscopic observations, validating the used models as a good agreement on the shape of the light emission profiles is found. The amount of released BeD is, however, somewhat overestimated.
