Reduced models for the maximum vertical force in a tokamak device

Nuclear 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.

Maximum likelihood bolometry for ASDEX upgrade experiments [PDF]

Bolometry is an essential diagnostic for calculating the power balances and for the understanding of different physical aspects of tokamak experiments. The reconstruction method based on the Maximum Likelihood (ML) principle, developed initially for JET,

Design and stress analysis of in-vessel saddle coils for MHD control in ASDEX Upgrade [PDF]

, 2008
A set of in-vessel saddle coils for MHD control in ASDEX Upgrade is described. A conventional coil design is chosen which employs a five turn square cross-section copper conductor with central cooling bore embedded in an epoxy resin.

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

, 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

Nuclear 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

EPJ 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

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

Nuclear 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.

Characterization and scaling of the tokamak edge transport barrier [PDF]

, 2012
Das Regime mit hohem Einschluss (H-Mode) in einem Tokamak Plasma zeichnet sich durch eine besondere Randregion aus. Auf einem kleinen räumlichen Bereich von 1-2 cm ändern sich die Eigenschaften des Plasmas signifikant.

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

Nuclear 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.
