Hydrogen Ion Cyclotron Wall Conditioning for Fuel Removal on TEXTOR and ASDEX Upgrade [PDF]

, 2012
Ion Cyclotron Wall Conditioning (ICWC), applicable in presence of the toroidal magnetic field, is envisaged in ITER to recover from disruptions, leaks and torus vents, for recycling control and for fuel removal.

Non-adiabatic passing electron response and outward impurity convection in gyrokinetic calculations of impurity transport in ASDEX upgrade plasmas [PDF]

, 2007
Gyrokinetic calculations with the GS2 code of impurity transport in ASDEX Upgrade H-mode plasmas are presented. A method to separate the diagonal and off-diagonal terms in the quasi-linear flux computed by the gyrokinetic code for a trace impurity is ...

Molecular contribution to the Dα emission in the divertor of the ASDEX Upgrade experiment

, 2007
Spectral line emission from the deuterium Balmer alpha line and from molecular deuterium in the Fulcher band, d(3)Pi(u)-> a(3)Sigma(+)(g), was studied in the outer divertor region of the ASDEX Upgrade plasma with a pair of relatively calibrated ...

Development and application of a predictive model for advanced tokamak scenario design

Nuclear Fusion
Advanced tokamak (AT) scenarios applying additional heating during the current ramp (early-heating) usually require many iterations if developed fully empirically.

Tungsten behaviour in radiatively cooled plasma discharges in ASDEX Upgrade [PDF]

, 2011
In the all W ASDEX Upgrade impurities are injected routinely for radiative cooling. Amongst the different species used, nitrogen has been shown to provide the best cooling effect, while maintaining or even improving the energy confinement.

Divertor enrichment of recycling impurity species (He, N2, Ne, Ar, Kr) in ASDEX Upgrade H-modes

Nuclear Fusion
Particle balance calculations are done for the seeding species N _2 , Ne, Ar, Kr as well as He with the aim of obtaining a realistic description of the divertor and core plasma impurity content.

2D and 3D studies of the X-divertor configuration in the future upper divertor of ASDEX upgrade

Nuclear Materials and Energy, 2019
ASDEX Upgrade is planning the installation of a pair of in-vessel coils in order to study alternative divertor configurations, like an X-divertor (XD) or a Snowflake (SF) in a machine with a high heating power compared to its size.
