ELM-suppressed High confinement mode (H-mode) from low confinement mode (L-mode)
phases with improved plasma performance. Such an edge-localized resonant magnetic
perturbation (ERMP)[1] is essential to minimize disruptive core components of low-n RMP
while maintaining its efficiency in ELM suppression for the entire period of H-mode. The core
reduction in ERMP also expands the ELM suppression window, increasing the safety margin …
