Abstract

The phenomenology of edge localized modes (ELM), an magnetohydrodynamics (MHD) instability occurring in the edge of H-mode plasmas in toroidal magnetic fusion experiments, is described. ELMs are important to obtain experimental control of the particle inventory of fusion plasmas. It is the aim of this article to review the experimental findings and theoretical models of ELMs and to establish a common classification together with a physical picture of the ELM phenomenon. In section 2, a phenomenological description of ELMs is given; based on the experimental results from various magnetic fusion experiments, a general classification is established. In section 3, existing theoretical models put forward to explain the physics of ELMs are reviewed. Based on this discussion, a physical picture of ELMs is established in section 4. Section 5 gives a summary and conclusions.
