Abstract

ELM experimental analysis on COMPASS-D, which has previously catalogued magnetic precursor behaviour, has been extended to consider effects in the SOL. ELM precursors are observed at the divertor. Profile changes are measured with high resolution and power and particle losses in ELMs are estimated. High speed videos of an ELM show a turbulent edge extending to the outboard limiter, in broad agreement with reciprocating probe observations. A model which describes well the magnetic features of the ELM, is being extended to include predictions of power deposition structure at the divertor target, for comparison with experimental data.
