Abstract

The reduction in size of Type I edge localized modes (ELM) with increasing density was explored for the purpose of studying the underlying transport of ELM energy. The conductive transport from the pedestal during an ELM decreased with increasing density, while the convective transport remained nearly constant. Magnetohydrodynamics (MHD) analysis of these discharges suggested that the smaller ELMs resulted from both a loss of edge bootstrap current at higher collisionality, and a narrower pedestal at high density.
