Comparison of Power Peposition Profiles During ELMs using Langmuir Probes and Infra-Red Camera Diagnostic at JET

Characterising the energy SOL transport during Type I ELMs in JET is of major interest to understand the empirical scaling of ELM heat fluxes to the ITER. The separation of the transient pulses of heat and particles arriving at the divertor target plates as a consequence of upstream ELM activity delivers insight of the convective and conductive transport channels. Such efforts require measurement of the ELM behaviour with both high temporal and spatial resolution, which can be achieved by infrared- and Langmuir probe measurements.
