Observation of tearing mode triggering by sawtooth crash with high-Z impurity accumulation in EAST

AIP Advances, 2023
The high-Z impurity accumulation in the plasma core could degrade the plasma performance and may affect sawtooth crash and trigger tearing modes (TMs) in experimental advanced superconducting tokamak (EAST).
