Abstract
Monte Carlo (MC) calculations of Cs+ transport in H2 are performed in order to establish a reliable transport cross section for momentum transfer. This system is important for plasma modeling in the context of the negative ion source design proposed for plasma heating in future nuclear fusion reactors. Two procedures are checked: use of the Langevin approximation based on realistic values of the physical parameters and a purely statistical, multi-parameter function allowing for shape variation at relative high energy. The two alternatives are discussed and final results provided to be used for negative source modeling.
