First SOLPS-ITER modelling of an X-point radiator in ITER

open access: yesNuclear Fusion
For the first time, an X -point radiating (XPR) regime using neon (Ne) seed impurity has been obtained in ITER modelling with the SOLPS-ITER code, including fluid drifts.

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.

First neutron spectroscopy measurements in the ASDEX Upgrade tokamak [PDF]

open access: yes, 2011
: A compact neutron spectrometer based on the liquid scintil-lator BC501A has been installed on the ASDEX Upgrade tokamak. The aim is to measure neutron energy distribution functions as footprints of fast ions distribution functions, generated mainly via

Review on ASDEX Upgrade operation with tungsten plasma facing components

open access: yesNuclear Materials and Energy
With the decision of ITER to start its operation with tungsten as plasma facing material also for the main chamber plasma facing components, the interest in the consequences of the use of W was strongly increased. Although many investigations had already

Characterization of 3-strap antennas in ASDEX Upgrade

open access: yesEPJ Web of Conferences, 2017
The response of the local RF current measured at limiters of 3-strap ICRF antenna to variations of power balance and phasing at fICRF=30MHz agrees qualitatively well with EM calculations by TOPICA and RAPLICASOL codes. Measurements of tungsten sputtering

Overview of initial negative triangularity plasma studies on the ASDEX Upgrade tokamak

open access: yesNuclear Fusion, 2022
An overview of results of negative triangularity (NT) studies from the ASDEX Upgrade tokamak (AUG) is given. Moderate values of the triangularity in the range of δ _average ≈ −0.2 have been obtained.

Fast-ion D-alpha measurements at ASDEX Upgrade [PDF]

open access: yes, 2011
A fast-ion D-alpha (FIDA) diagnostic has been developed for the fully tungsten coated ASDEX Upgrade (AUG) tokamak using 25 toroidally viewing lines of sight and featuring a temporal resolution of 10 ms.

The quasi-continuous exhaust regime in JET

open access: yesNuclear Fusion
The quasi-continuous exhaust (QCE) regime is a regime that is naturally type-I ELM-free. It combines the high density at the plasma edge needed for power exhaust with the high normalised energy confinement typical for H-mode operation.

Overview of the ASDEX Upgrade results

open access: yesNuclear Fusion
After a 26-month vent ASDEX Upgrade (AUG) went back in operation with a newly designed upper W-divertor suitable for alternative divertor configurations (featuring in-vessel coils and cryo-pump).
