A detailed analysis of neutral atom recycling and pedestal fueling in a DIII-D _J. Luxon, Nucl.
Fusion 42, 614 _2002__ high-confinement mode discharge is presented. Experimental data and
two-dimensional _2D_ edge plasma fluid code calculations are employed to provide ion wall
recycling and recombination neutral sources and background edge plasma parameters for a 2D edge
neutral code calculation of detailed neutral density, ionization, and charge-exchange distributions
throughout the edge pedestal, scrape-off layer and surrounding halo region, divertor, and private flux
regions. The effectiveness of the different neutral sources for fueling the confined plasma is
evaluated
