Dielectronic recombinaation, the inverse of autoionization, is a process leading to significant power loss in CTR plasmas. Although it is known that dielectronic recombination proceeds via autoionization Rydberg states, few data exist on autoionizing states and how they are affected by conditions found in a CTR plasma. Under this research program we have been using a novel laser excitation technique developed at SRI to study autoionizing states and the perturbing effects of electric fields found in CTR plasmas. We describe experimental investigations of the spectroscopy of autoionizing Rydberg states, the energy analysis of electrons ejected from autoionizing states, autoionizing in electric fields, and the autoionization induced by an electric field. 33 refs., 16 figs.
