  1. Issues in ELM control using pellet and RMP Final goal: to establish ELM mitigation technique with • No degradation of pedestal and H-mode performance to achieve Q=10 plasma • Compatibility with ITER hardware • Location of ELM control coils (urgent issue in ITER DR8. “Assure that space for ELM control windings is reserved”) (ITER coil issues: Tuesday afternoon) • Fueling/pumping capability (urgent issue in ITER DR9. “Impact of increased gas loads due to pellet pacing on pumping systems affecting building size”) • Wide operational window covering all ITER scenarios

  2. Operational windows depend on resonant condition=> Can we operate any q95 value in ITER?=> How to maximize/optimize operational windows?

  3. Sugihara et al, JSPF meeting in 2006 Operational windows depend on penetration depth=> How robust is minimum lp/Dped?=> Is it possible to reduce lp/Dped?
