Modelling and experimental studies of impurity control in jet X-point configurations
Description
A modelling procedure of the edge plasma is proposed. It is applied to the JET experimental data from pulse number 15797, which has a short H-mode. A classical plasma transport model is presented. The forces acting on the impurities are calculated. A heat transport equation and an alternative formulation when convection dominates conduction are presented. The model and the experimental results are compared. The results suggest the shielding of carbon impurities released at the plate and that the effect of the power at the scrape-off layer is not strong
