ERO and PIC simulations of gross and net erosion of tungsten in the outer strike-point region of ASDEX Upgrade

open access: yesNuclear Materials and Energy, 2017
We have modelled net and gross erosion of W in low-density l-mode plasmas in the low-field side strike point region of ASDEX Upgrade by ERO and Particle-in-Cell (PIC) simulations.

Heat transport at the boundary of ASDEX Upgrade [PDF]

open access: yesPlasma Physics and Controlled Fusion, 1997
The flow of heat in the scrape-off layer (SOL) region of ASDEX Upgrade is investigated and compared with simple modelling. Parallel heat transport is found to be consistent with electron heat conduction based on Spitzer - H?rm conductivity. Cross-field heat transport is characterized using radial e-folding distances for power, temperature and plasma ...

X-point radiator control and its dynamics in ASDEX Upgrade and JET deuterium–tritium discharges

open access: yesNuclear Fusion
Control of heat exhaust is essential for the operation of power producing fusion reactors. Here, we present results of heat exhaust feedback control experiments in JET and AUG.

Validation of a full-plasma integrated modeling approach on ASDEX Upgrade

open access: yesNuclear Fusion, 2021
In this work we present the extensive validation of a refined version of the integrated model based on engineering parameters (IMEP) introduced in reference (Luda et al 2020 Nucl. Fusion 60 036023).

Reduced models for the maximum vertical force in a tokamak device

open access: yesNuclear Fusion
A formula was suggested in Miyamoto et al (2011 Plasma Phys. Control. Fusion 53 082001) to calculate the total maximum vertical force due to a vertical displacement event in a tokamak device without modeling the whole phenomenon.

A study on the density shoulder formation in the SOL of H-mode plasmas

open access: yesNuclear Materials and Energy, 2017
The term “shoulder formation” refers to an increase of the density decay length in the scrape-off layer (SOL) observed in many tokamaks during L-mode operation when a density threshold is reached.

Quiescent regions below the X-point in ASDEX upgrade

open access: yesPlasma Physics and Controlled Fusion, 2021
Probe measurements of plasma fluctuations in the divertor region of ASDEX Upgrade reveal the existence of two quiescent regions close to the separatrix: one on the low field side scrape-off layer and one on the high field side of the private flux region.
