  1. Thermal energy confinement in ELMy H-mode in MAST M Valovič, R Akers, C Brickley EURATOM/UKAEA Association, Culham, Abingdon, UK 4th ITPA Meeting on Confinement Databases and Modelling St Petersburg, 8-11 April 2003

  2. Monte-Carlo calculation of thermal energy confinement for data in pedestal and global DBs Codes: TRANSP or LOCUST WTH=WMHD - WFFORM PNBI = PINJ - shine through PFLOSS= CX loss(ext+int) + orbit loss Shot WMHD WFFORM [kJ] % PINJ PNBI PFLOSS [MW] (PNBI-PINJ+PFLOSS)/PINJ % 6249 69 10 14 1.47 1.47 0.27 18 6252 78 11 15 1.75 1.64 0.26 21 6271 90 19 21 1.95 1.91 0.36 20 6761 74 6.4 8 1.52 1.47 0.23 18 6762 75 9.1 12 1.51 1.51 0.19 13 M Valovic, 4th ITPA Meeting on CD&M, St Petersburg, 8-11 April 2003

  3. Beam power deposition calculated by TRANSP M Valovic, 4th ITPA Meeting on CD&M, St Petersburg, 8-11 April 2003

  4. H-mode confinement database expanded during 2003 • New data with Te and Ti profiles both in the core and pedestal • Include Ip scan 0.6-0.9MA M Valovic, 4th ITPA Meeting on CD&M, St Petersburg, 8-11 April 2003
