Power and Particle Exhaust Control in All W ASDEX Upgrade

R. Neu, C. Fuchs, A. Kallenbach, R. Dux et autres

Independent of the plasma facing materials in future fusion devices impurity seeding will become an inevitable element of the operation to protect the divertor from excessive heat loads. A very beneficial behaviour in terms of reduced power loads, moderate impurity concentrations and …

Confinement of ‘improved H-modes’ in the all-tungsten ASDEX Upgrade with nitrogen seeding

J. Schweinzer, A. C. C. Sips, G. Tardini, P. A. Schneider et autres

In ASDEX Upgrade the compatibility of improved H-modes with an all-W wall has been demonstrated. Under boronized conditions light impurities and the radiated power fraction in the divertor were reduced, requiring N seeding to cool the divertor plasma. The impurity seeding does …

The halo current in ASDEX Upgrade

G. Pautasso, L. Giannone, O. Gruber, A. Herrmann et autres

Due to the complexity of the phenomena involved, a self-consistent physical model for the prediction of the halo current is not available. Therefore the ITER specifications of the spatial distribution and evolution of the halo current rely on empirical assumptions. This paper …

Plasma induced arcs in remote areas of ASDEX Upgrade

A. Herrmann, O. Gruber, U. Seidel, T. Lunt et autres

Introduction Arcing as a phenomenon at the first wall in fusion experiments is known for more than 30 years [1]. The occurrence of arcs was concluded from arc tracks found during in-vessel inspections and in post mortem laboratory investigations. In ASDEX Upgrade …
