Intrinsic impurity transport modelling versus experiment Intrinsic impurity transport modelling versus experiment – R. Neu
Introduction and plans– 13.30 E. Fable:
Turbulent impurity transport in the core of tokamaks, physical mecha-nisms, ongoing validation efforts, potential impact on plasma discharges
– 14.05 R. Dux Impurity transport in the ETB of AUG H-Mode discharges
– 14.40 Coffee – 14.55 M. Valisa:
Achievements and open issues in impurity profile control at JET – 15.30 C. Giroud
Impurity transport characterisation in JET operational scenarios

Manning Issues
Preliminary Results from the Manning SelectionPreliminary Results from the Manning Selection good coverage (personnel, dates) of competencies SC selection close to being finalised Detailed analysis for identification of gaps and shortages ongoing TSL selection had to be restricted to 12 candidates due to available
number of slots (min. stay 60 days)
Next steps in the manning selectionNext steps in the manning selection TFL/(CSU) meetings on the 8th, 11th and 12th of April to finalise Allocated time for parastic experiments in restart (interaction
TFL/CSU/POG)

Red: NO parasitic experiments
White: Parasitic experiment with possibility of pulse time.
Yellow: monitoring experiment ONLY
Restart integration
This phase should try to put in place the conditionning/breakdown diagnostic tools
