  1. E1/E2 meeting on ‘Intrinsic impurity transport modelling versus experiment’ R. Neu E1/E2 Meeting, 7/4/11

  2. Introduction • Manning • 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

  3. Manning Issues • Preliminary 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 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)

  4. Restart integration Red: NO parasitic experiments Yellow: monitoring experiment ONLY White: Parasitic experiment with possibility of pulse time. Restart 1 W31 Parasitic Experiments to be filled This phase should try to put in place the conditionning/breakdown diagnostic tools

  5. Impurity Transport • One of main ILW goals: Demonstrate/investigate feasibilty of W divertor operation in baseline and advanced scenarios • Dedicated experiments as well as long term monitoring envisaged • Two extremes could ‘hamper’ investigations: - strong negative impact of central W radiation:  change of experiment strategy could be necessary - no measurable influence of W:  loss of interest by ‘non experts’, design of dedicated discharges • Supporting investigations on intrinsic impurities by injection of tracers (LBO, gas puffs)

  6. Dedicated sessions for impurity transport investigations Category 1 • Ex-2.2.1 Determination and control of the intrinsic impurity composition in the full W divertor (4 sessions) • Ex-2.2.2 W screening, peaking and control(5 sessions) • Ex-3.2.5 Effect of SOL transport, pedestal and ELMs on impurity transport(C30) Category 2 • Ex-2.1.6 Characterisation of ICRF heating with the ILW • Ex-2.2.4 Impurity seeding in preparation for ITER • Ex-1.1.7 Divertor W erosion and ELM induced sputtering • Ex-1.1.8 Long term evolution of W erosion and migration • …

  7. Parasitic experiments for impurity transport investigations Parasitic • Px-2.1.3 Control of impurities accumulation during current rise in diverted plasmas • …
