Definition
The term, in context
AI-assisted draft · approved dataset
EAST (Experimental Advanced Superconducting Tokamak) is a Chinese magnetic-confinement fusion research reactor that uses superconducting magnets to hold hydrogen plasma in a toroidal shape, and its 1,066-second steady-state high-confinement-mode (H-mode) plasma run demonstrated sustained, stable plasma confinement over a duration far longer than most fusion devices achieve.
