NF paper on H-mode confinement DB3 Darren McDonald
Aims and overview • Paper describes updates to and analysis of DB3 from 1994 – 2004. • Data from 18 machines of different sizes and shapes. • DB now contains D-T, low A, dim. Scan… data • + more data from range of divertors and high d, n and Ip. • Physics: shape, fuelling, core and edge, dimensionless parameters, comparison with 1d transport codes • Statistics: error estimates, EIV, reducing correlations • Key aim of DB is ITER predictions: recommended scalings
Structure • Introduction • Changes to DB3 (Machine descriptions) • DB3: subsets, errors, condition • E power law scalings (OLS, EIV,r*) • Two term models • Other models: offsets, other vars, … • ITER: scalings, intervals • Conclusion A. Summary of new variables + link to website
Machine overviews • Thank you: generally homogeneous (~1-2 pages) • Missing data • Machine overview/reference: JT-60U, TFTR • Selection method: MAST • Diagnostics/analysis: DIII-D, NSTX, T-10 • Pedestal data: AUG, C-Mod, DIII-D, JET, JT-60U • Refs: AUG, C-Mod, NSTX, TCV, TFTR • Reduction • Refs and diagnostic description: JET
Conclusion • Paper provides a discussion of construction and analysis work on DB3, including two term models • This meeting: • discussion of pre-draft • some help with machine descriptions • First full draft: November • Submission: early 2006
