Extension of ELM suppression window using RMPs in EAST

Nuclear Fusion, 2023
The q _95 window for Type-I edge localized modes (ELMs) suppression using n  = 4 even parity resonant magnetic perturbations (RMPs) has been significantly expanded to the ranges [3.9, 4.1] and [4.2, 4.8] in EAST while maintaining good confinement, which ...

Integrated RMP-based ELM-crash-control process for plasma performance enhancement during ELM crash suppression in KSTAR

Nuclear Fusion, 2023
The integrated Resonant Magnetic Perturbation (RMP)-based Edge-Localized Mode (ELM)-crash-control process aims to enhance the plasma performance during the RMP-driven ELM crash suppression, where the RMP induces an unwanted confinement degradation.

Edge turbulence transport during ELM suppression with n = 4 resonant magnetic perturbation on EAST

Nuclear Fusion, 2023
The edge turbulence characteristics and the induced radial transport have been investigated in edge localized mode (ELM) suppression by using the $n = $ 4 resonant magnetic perturbation coils on EAST, with ${q_{95}} = $ 3.6 and the electron ...
