Abstract

The paper reviews recent theoretical and experimental results focussing on the identification of the key factors controlling ELM energy and particle losses both in natural ELMs and in the presence of external controlling mechanisms. The theoretical description of the most studied Type I ELMs is progressing from linear MHD stability analysis for peeling and ballooning modes to the non-linear explosive models and transport codes. Present theories cannot predict the ELM size self-consistently, however they pointed out the benefit of the high plasma shaping, high q95 and high pedestal density in reducing the ELM affected area. The experimental data also suggest that the conductive energy losses in Type I ELM can be controlled by working in specific plasma conditions.
