The high field side high density region in SOLPS-modeling of nitrogen-seeded H-modes in ASDEX Upgrade

Nuclear Materials and Energy, 2017
The understanding of divertor physics and the evolution of divertor detachment is crucial for developing the capability to model power exhaust in current experiments and reliably predict it for future fusion devices.

Simulations of ELM-induced tungsten melt flow across misaligned plasma-facing components

Nuclear Fusion
A computational fluid dynamics model of ELM-induced tungsten melt flow across a gap between misaligned plasma-facing components is validated against data from dedicated leading-edge exposures in the ASDEX Upgrade tokamak.

Assessment of particle and heat loads to the upper open divertor in ASDEX Upgrade in favourable and unfavourable toroidal magnetic field directions

Nuclear Materials and Energy, 2019
Pairs of ASDEX Upgrade L-mode discharges with the toroidal magnetic field, BT, in the forward and reverse directions have been used to study the impact of neoclassical drifts on the divertor plasma conditions and detachment.

Anisotropic regularization for inversion of fast-ion loss detector measurements

Nuclear Fusion
We introduce an anisotropic regularization framework for the reconstruction of distribution functions from measurements, utilizing an approach that applies distinct regularization techniques such as non-negative constrained Tikhonov, total variation, and

Investigations on boronisation in the full-tungsten ASDEX UPGRADE

Nuclear Materials and Energy
Conditioning of the Plasma-Facing Surfaces (PFSs) in fusion devices is essential for reliable plasma operation. In ASDEX Upgrade (AUG), boronisation by a glow discharge in helium (He) with 10% of deuterated diborane is used as a standard wall ...
