1. 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?

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

3. 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
