  1. Status of Public Release PR0X of Profile Database • C M Roach • Euratom/UKAEA Fusion Association, • Culham Science Centre, Abingdon, Oxon, OX14 3DB, UK • Public Release of Profile Database PR0X • Accompanying NF Paper Seek progress through discussions this meeting! • This work was jointly funded by the EPSRC and EURATOM

  2. Path to PR0X • Machine representatives from each donor machine have been asked to: • confirm permission for public release of post-PR98 discharges • contribute to paper accompanying PR0X iii. ensure last few PR0X discharges comply with variables agreed 2005. NB affects only d3d (19) and tftr (1 or 81 if include PR98) http://tokamak-profiledb.ukaea.org.uk/RESTRICTED/conversion/mainTable.php • Assemble Paper to accompany PR0X and submit to NF • Fix X and make available the Public Release PR0X

  3. NF Paper to Accompany PR0X PR0X NF paper: Similar in purpose to PR98 paper by Boucher et al, NF 40 1955 (2000). Intended to provide a compact overview of the profile database and advertise this valuable resource to the whole community. Sketch outline of the paper was discussed and agreed at Chengdu • introduction and history of database (CMR) • describe new PR0X discharges (machine representatives) • describe database access and tools (CMR) • review main modelling using profile database since PR98 (CMR)

  5. Review of Modelling with Profile Database • BRIEF summary overview of modelling using profile database since PR98. • Memory + Boucher (2000) citations (“Google Scholar”, “Web of Science”, ORNL) •  ~30 papers • Removing most peripheral citations, filters down to: • ITBs • J. W. Connor et al., `A review of internal transport barrier physics for steady-state operation of tokamaks’, Nuclear Fusion 44, R1 (2004). • P. Gohil et al., ‘Increased understanding of the dynamics and transport in ITB plasmas from multimachine comparisons’, Nuclear Fusion 43, 708 (2003). • C. Bourdelle et al., `Impact of the  parameter on the microstability of internal transport barriers’, Nuclear Fusion 45, 110 (2005). • J. E. Kinsey, G. M. Staebler, and R. E. Waltz, `Predicting core and edge transport barriers in tokamaks using the glf23 drift-wave transport model’, Phys Plasmas 12, 052503 (2005). • Advanced Scenarios, Hybrid, Steady State • F. Imbeaux et al., `Multi-machine transport analysis of hybrid discharges from the ITPA profile database’, Plasma Physics and Controlled Fusion 47, B179 (2005). • J. E.

  7. Other Issues • Whether to Include ITER Scenarios? • ITER model predictions will evolve, while present device data should be robust. • => publish ITER scenarios separately? (use profile database framework) Preliminary Author List: F Ryter, J Stober, C Greenfield, J Kinsey, M Murakami, E Doyle, G Bracco, M Romanelli, V Parail, P Stubberfield, I Voitsekovitch, Y Sakamoto, T Fujita, T Fukuda, A R Field, C Brickley, G M D Hogeweij, A Chudnovsky, R Budny, T Aniel, F Imbeaux, G T Hoang, J Ongena, C M Roach, M Walters, J Carlsson, T Fredian, M Greenwald, J Stillerman,W A Houlberg include full membership of ITPA Transport and CDBM Groups? additions/deletions/changes?

  8. Conclusions Status of PR0X Data: • 102/122 PR0X discharges are ready for publication now • a fewkey discharges (d3d, tftr) still to comply with agreed variables ... “shame to spoil the ship for a ha’penny worth of tar!” NF Paper Status: • discharge descriptions are rolling in from machines, and most are promised over the coming few weeks • CMR will add content to: Introduction, Data access and tools, Review of Modelling, Conclusion. (early summer) • accumulating draft available for your perusal at http://tokamak-profiledb.ukaea.org.uk/RESTRICTED/ • updated drafts will be posted to same URL + advertised by email Commitments for missing elements this meeting?
