Results from DIII-D

Activities at DIII-D related to the 2000-04 IAEA CRP on Atomic Data for Plasma Diagnostics have included: Identification of neutral atomic and molecular carbon data needed for spectroscopic studies of carbon sources in tokamaks with graphite walls; Development of a numerical hydrocarbon (primarily methane) dissociation-transport model for studying the effects of chemical sputtering and transport in tokamaks with graphite walls; Establishing atomic data needs associated with deuterium recycling from graphite walls; Developing numerical models of lithium sputtering and transport at the target plates of a poloidally diverted tokamak and the atomic data needed for these models; Assessment of fluorine charge exchange data for spectroscopic studies of transport processes in the pedestal region of high performance tokamak plasmas; The evaluation of a divertor CER diagnostic system for DIII-D using atomic data produced specifically for this purpose
