Key Results from SOL H-Mode Characterization Study

This study presents key findings from SOL H-mode characterization, comparing data from old and new shots, and analyzing data from target Langmuir probes. The aim is to repeat mode #26730 modeled by SOLPS and obtain new data from LPs RCPIR. The analysis includes upstream profiles of ne and Te, ELM time evolution, and J0 profiles in the inner and outer targets. Thank you for your attention. Perpendicular heat flux and target profiles are also discussed.

  1. Some key results from SOL H-mode characterisation Barbora Gulejová, Richard Pitts, Roland Behn, Jan Horáček OUTLINE • * Experiments - motivation • * Comparison of data from old and new shots • * Analysis of data from target langmuir probes Barbora Gulejova

  2. AIM: repetition of #26730 modeled by SOLPS- new data required from : LPs RCPIR 26730-old 31832-new Egde TS laser beam RCP LP + SOLPS LP Barbora Gulejova
