Plasma wall interaction during ELMs in JET

Funded under: FP7-EURATOM

Abstract

Particle and energy fluxes during transient events such as ELMs (edge localized modes) and disruptions need to be controlled to prevent damage to the Plasma Facing Components. A new wide angle infrared and visible diagnostic has been installed on JET which permits the observation of the plasma wall interaction in the main chamber. First observations of the interaction of ELMs with the main chamber are presented. Areas of interaction vary with the magnetic configuration and also within a single shot. A part of the ELM energy is deposited outside the divertor, mainly on the inner baffle, the outer limiter and the upper limiters.
