Simplified mass ablation and relocation treatment for pellet injection optimization

Polevoi, A. R.*; Shimada, Michiya

A simplified mass ablation and relocation treatment of high field side/low field side pellet injection is proposed. It includes a model of pellet ablation, parallel flow model for the attached ablation channel and a simplified magnetohydrodynamic (MHD) pellet displacement model. This treatment reveals satisfactory agreement with the present day experiments on ASDEX-U and DIII-D tokamaks. The model provides the optimisation directions for deep plasma fuelling in experiments. Calculation with ITER parameters suggests that deep penetration up to ~ 60-70% of minor radius is possible at modest velocity <0.5 km/s with high field side injection.
