High Beta Profile Data for ISHPDB: Contributions from the W7-AS Stellarator Project

This document presents the high beta profile data for the ISHPDB, focusing on contributions from various researchers associated with the W7-AS stellarator project. The data covers key parameters from significant shots, including detailed plasma characteristics, pressure profiles, and heating power profiles. It summarizes the status of validation analyses and mapping efforts for shots #54022 and #54023. Collaboration insights from the 5th Coordinated Working Group Meeting for Stellarator/Heliotron Studies, held in July 2009, are also discussed, along with resources available on the ISHPDB public webpage.

  6. W7-AS High-b Shot #54023@0.35 s- ne, Te – Profiles (Ruby Thomson, Raw Data) - ● ruby Thomson system set up for inboard edge plasma observation ● limited core-profile data

  7. W7-AS High-b Shot #54023@0.35 s- mapped ne, Te – Profiles (Ruby Thomson) from standard analysis - ● pressure Profile used to check mapping (VMEC) ● but: dedicated VMEC runs required for high-b data mapping

  8. W7-AS High-b Shot #54022@0.35 s- ne, Te – Profiles (Ruby Thomson, Raw Data) - ● ruby Thomson system set up for inboard edge plasma observation ● limited core-profile data

  9. W7-AS High-b Shot #54022@0.35 s- mapped ne, Te – Profiles (Ruby Thomson) from standard analysis - ● pressure Profile used to check mapping (VMEC) ● but: dedicated VMEC runs required for high-b data mapping

  10. W7-AS High-b Shot #54022@0.35 s- some more parameters from standard Thomson Fits - PS plateau lmfp

  14. W7-AS High-b Shot #54022@0.35 s- Status of ne, Te – Profile Validation Analysis - ● dedicated VMEC runs for mapping available for #54022 ● profile fitting ?

  15. W7-AS high beta profile data for the ISHPDB- Present Status - http://xanthippe.ipp-hgw.mpg.de/ISS/public/index.html

  16. Summary ● Two high-b shots being prepared for ISHPDB ● W7-AS Shot #54022 mapped by dedicated VMEC equilibrium, validation stage 3 finished ● W7-AS Shot #54023 still requires advanced mapping and fitting ● Profile fits to be made available (data tables)? Or tool to be provided for fitting mapped profile data individually? ● NBI heating power profiles available ● Data and infos available on ISHPDB public webpage http://xanthippe.ipp-hgw.mpg.de/ISS/public/index.html but not yet complete !
