Calculation of observable quantities using a divertor impurity interpretive code, DIVIMP

摘要: Our picture of divertor edge plasma behaviour is largely theoretical with little experimental confirmation. Questions exist regard to impurity production mechanisms, sputtering yields, ion temperatures, parallel temperature gradients, the existence flow reversal, cross-field diffusion coefficients, etc. Spatial distributions ions successive charge states in edge, when interpreted an production/transport code, provide a basis for discriminating amongst various possibilities. In this paper, example case, wide range models/assumptions about examined effect on spectroscopic intensities C+ through C5+ vicinity targets. It shown that single viewing location can be sufficient discriminate most made behaviour. More refined discrimination would require additional locations and diagnostics, such as Doppler measurements.
