Impact of magnetic islands on edge plasma rotation in J-TEXT tokamak

Puntos clave

• Edge plasma rotation changes in the presence of magnetic islands, affecting confinement and stability.
• Key evidence indicates a significant variation in rotation speed, observed over multiple experiments.
• Analysis was conducted using observational techniques across the J-TEXT tokamak facility, assessing various magnetic configurations.
• These findings highlight the need for further exploration of magnetic structures' effects on plasma behavior.
