ITPA Pedestal & Edge Physics Topical Group (P&EP)
Rajesh Maingi (chair), Hajime Urano (deputy), and Guido Huijsmans (ITER Dep. Chair)
In order to develop the physics basis for ITER operation, the Pedestal and Edge Physics Topical Group shall coordinate pedestal plasma physics research: initiate collaborative research activities among international fusion research establishments to improve the understanding of pedestal physics, with a focus on the key questions for ITER; develop, maintain and analyze the international pedestal databases, assessing the implications for ITER; and carry out theory and modelling, integrated with experimental activity, to advance scientific knowledge and so reduce uncertainties in predictions for fusion devices, such as ITER. Based on these activities, the Topical Group shall make recommendations for the physics research areas and methodologies to address key remaining questions for pedestal fusion research. Since the region treated by the Pedestal and Edge Physics Topical Group is the boundary between the core and the Scrape-Off-Layer (SOL)/divertor regions, and the topic has implications for ITER diagnostics, as well as overlaps with magnetohydrodynamics (MHD), the group shall seek to benefit from collaborative activities with the other Topical Groups.
