Kirk, A., Wilson, H.R., Counsell, G.F., Akers, R., Arends, E., Cowley, S.C., Dowling, J., Lloyd, B., Price, M. and Walsh, M. (2004) Spatial and Temporal Structure of Edge-Localized Modes. Physical Review Letters, 92 (24). pp. 245002-1. ISSN 1079-7114
This Letter provides information on the spatial and temporal structure of periodic eruptions observed in magnetically confined laboratory fusion plasmas, called edge-localized modes (ELMs), and highlights similarities with solar eruptions. Taken together, the observations presented in this Letter provide strong evidence for ELMs being associated with a filamentlike structure. These filaments are extended along a field line, are generated on a 100 μs time scale, erupt from the outboard side, and connect back into the plasma. Such structures are predicted by a theoretical model based on the “ballooning” instability, developed for both solar and tokamak applications.
