Abstract

A simple one-dimensional model for sputtering from the surface of a molybdenum limiter has been developed. Sources of sputtering included in this model are due to thermal ions and the subsequent self-sputtering that follows. The resultant molybdenum source rates match those calculated based on molybdenum line emission data from the main plasma coupled with an anomalous impurity diffusion coefficient. A review of the source rate dependence on plasma parameters is also included.
