A brief overview of the physical mechanisms of negative ion production in a hydrogen/deuterium plasma is given. An analytical model is presented which describes many of the features observed in experiments on the production of negative ions in these plasma sources. This model leads to a prediction of the performance capabilities of these sources. Comparison of experimental results for the production of H- and D- ions is also presented.
