Abstract
The scrape-off layer of a JET X-point discharge has been modelled with a multi-fluid plasma model linked to a Monte Carlo model for the neutral deuterium and impurity species. A relatively complete set of boundary plasma data has been obtained, is shown to be consistent within the experimental uncertainties and suggests significant shielding of the carbon impurities released at the graphite target plate. The agreement with the main experimental parameters, n e, T e, is good, as also is the match with the observed radiation and impurity distribution provided that a rather large plasma flow is included in the model.
