1. Parameter similarity studies in JET, ASDEX Upgrade and ALCATOR C-Mod

Author

Suttrop, W., Horton, L., Hubbard, A., McDonald, D., Barnsley, R., Beurskens, M., Bonoli, P., Chareau, J., Cordey, J., Hughes, J., Lomas, P., Maddison, G., Meigs, A., Meo, F., Mossessian, D., Neu, R., Noterdaeme, J., Parail, V., Ryter, F., Schweinzer, J., Stamp, M., Strachan, J., Stober, J., Wukitch, S., ASDEX Upgrade Team, ALCATOR C-Mod Team, and JET EFDA Contributors

Abstract

Similarity plasmas are studied in JET, ASDEX Upgrade and ALCATOR C-Mod to test the validity of dimensional constraints for core profiles and profiles at the plasma edge in H-modes with and without large dge Localised Modes and at the H-mode transition. Core and H-mode edge profiles in the studied comparison pairs of pulses match within uncertainties. Identical scaled H-mode threshold and edge MHD behaviour is obtained in JET and ASDEX Upgrade for same edge Ρ*, ν*,and β. In contrast, constant edge temperature, required for identity of atomic cross sections, does not describe operational regime boundaries in the two machines. First attempts have been made to reproduce ALCATOR C-Mod EDA-mode plasmas in ASDEX Upgrade; the results of the best matches obtained are reported.

Abstract

The recent development of real-time measurements and control tools in JET has enhanced the reliability and reproducibility of the relevant ITER scenarios. Diagnostics such as charge exchange, interfero-polarimetry, electron cyclotron emission have been upgraded for real-time measurements. In addition, real-time processes like magnetic equilibrium and q profile reconstruction have been developed and applied successfully in real-time q profile control experiments using model based control techniques. Plasma operation and control against magnetohydrodynamic instabilities are also benefiting from these new systems. The experience gained at JET in the field of real-time measurement and control experiments operation constitutes a very useful basis for the future operation of ITER scenarios.
