Pedestal Structure and Control TSG

Meeting files

Overall TSG objective: Control and optimize the H-mode pedestal and ELMs

Thrust 1 - Assess and control pedestal structure, edge transport and stability

Primary Related Programmatic Milestones

R(16-1): Assess H-mode energy confinement, pedestal, and scrape-off-layer characteristics with higher BT, Ip and NBI heating power

R(16-3): Develop the physics and operational tools for obtaining high-performance discharges in NSTX-U
