9th ITPA Confinement Database and Modelling Topical Physics Group
meeting in St. Petersburg 1/5
NF paper on H-mode confinement DB3
Darren McDonald
9th ITPA Confinement Database and Modelling Topical Physics Group
meeting in St. Petersburg 2/5
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 , 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
