Integration of ITER "Matrix" for Enhanced ELM Avoidance and Pedestal Studies in Fusion Research

The ITER "matrix" serves as the backbone for critical aspects of the experimental program, enabling targeted investigations into ELM avoidance, pellet pacing, and operational scenarios under high current conditions. This flexible framework facilitates the selection of relevant and comparable experimental setups, ensuring effective data integration. Upcoming presentations will further elucidate the matrix's role in supporting studies on H-mode pedestal erosion, ion losses, ELM loads using upgraded diagnostics, and connections to momentum transport research, comparing methodologies like EFCC and pellets.

Presentation Transcript

  1. (ITER Like Wall)

  2. (ITER Like Wall)

  3. This is the back bone of a large part of the program. This “matrix” allows follow up experiments (e.g. ELM avoidance, pellet pacing, pp scenario integration) to chose a working relevant and comparable scenario in the regime of interest (e.g. high current)

  4. See separate presentation tomorrow

  5. Demonstrate method is suitable at all • Integration into ITER relevant scenario available from “matrix” • More tomorrow in separate talk

  6. H-mode TF RIPPLE studies: pedestal erosion - due to ion losses? • Gain information on pedestal profiles (missing to date) • ELM loads (use upgrade diagnostics, e.g. IR camera) • Connect to rotation & momentum transport studies • Compare to other “pedestal erosion” techniques like EFCC, pellets,…
