Edge Localized Modes and Fluctuations in the JET SOL Region
Understanding the impact of Edge Localized Modes (ELMs) induced particle and energy fluxes in the divertor plates remains as one of the major concerns in the fusion community for future devices like ITER. ELMs affect both energy and particle confinement, thus providing particle control in improved confinement regimes. However, large amplitude ELM events might lead to unacceptable power loads in the divertor plates. The possible link between the amplitude and the radial propagation of ELMs might have an important consequence in the extrapolation of the impact of ELM in the divertor plates on future devices. This paper presents the investigation of the radial propagation of ELMs in the JET Scrape-Off Layer (SOL) region.
