Divertor Heat Load in ASDEX Upgrade L-Mode in Presence of External Magnetic Perturbation [PDF]
, 2017 Power exhaust is one of the major challenges for a future fusion device. Applying a non-axisymmetric external magnetic perturbation is one technique that is studied in order to mitigate or suppress large edge localized modes which accompany the high ...

Pellet-fueled I-mode plasmas in ASDEX Upgrade
Nuclear Fusion, 2023 This letter reports on the efforts carried out at the ASDEX Upgrade tokamak to integrate I-mode plasmas with pellet fueling and to increase the I-mode Greenwald fraction $f_{\mathrm{GW}}$ , two important requirements for any DEMO operational scenario ...

I-mode studies at ASDEX Upgrade: L-I and I-H transitions, pedestal and confinement properties [PDF]
, 2016 The I-mode is a plasma regime obtained when the usual L-H power threshold is high, e.g. with unfavourable ion B ∇ direction. It is characterised by the development of a temperature pedestal while the density remains roughly as in the L-mode ...

ASDEX Upgrade's new plasma control scheme [PDF]
Fusion Engineering and Design, 2006 Abstract ASDEX Upgrade is a medium sized tokamak experiment investigating highly shaped plasma and advanced scenarios to be extrapolated for ITER. Eleven independent magnetic coils allow for proper shaping and plasma current control. For plasma heating and current drive eight NBI beam lines, two ICRH antenna pairs and four ECRH gyrotrons are ...

Optimization of the computation of total and local radiated power at ASDEX Upgrade
Nuclear Fusion, 2021 Radiation losses are measured as a line integrated quantity from the plasma, on ASDEX Upgrade using foil bolometers. Based on these measurements, the computation of the radiated power from either the whole volume or any sub region requires post ...
