Abstract:The use of non-fuel pellets is desirable for ITER due to its decoupling ELM pacing from fueling. In this paper, the Neutral Gas Shielding Model (Parks et al., Nucl, Fusion 34(1994)417) has been applied to the ablation of Li pellets in the H-mode pedestal region. The results show that the injection velocity of pellets is a more convenient parameter for one to control the deposition profile and location of the injected species in the pedestal. The information obtained from this work can further be used as input for fluid transport codes to track the trajectories of the impurity species or as input for advanced MHD codes for better understanding the non-linear destabilization of ELMs.
