Suppression of ELM’s is a major issue for ITER and beyond Effect of LHCD on ELM’s Suppression of ELM’s is a major issue for ITER and beyond LHCD has been shown to affect the pedestal in CMOD Can LHCD affect ELM’s?

Requires unusual plasma shape Is this compatible with high power LHCD? Requires low collisionality High edge Te may aid LH damping

Plan Establish ELMing H-Mode plasma Verify ability to couple LH power Scan power and phasing to look for effect Scan pedestal parameters to maximize effect
