Evaluation of impurity densities from charge exchange recombination spectroscopy measurements at ASDEX Upgrade
(Institute of Physics Publishing, 2018-07-26)
At ASDEX upgrade (AUG) a new framework for the evaluation of impurity densities based on measurements from charge exchange recombination spectroscopy (CXRS) diagnostics has been developed. The charge exchange impurity ...

A forward model for the helium plume effect and the interpretation of helium charge exchange measurements at ASDEX Upgrade
(IOP Science, 2018-03-23)
The analysis of the charge exchange measurements of helium is hindered by an additional emission contributing to the spectra, the helium ‘plume’ emission (Fonck et al 1984 Phys. Rev. A 29 3288), which complicates the ...

Ion heat transport dynamics during edge localized mode cycles at ASDEX Upgrade
(IOP Publishing, 2018)
The edge ion heat transport is analyzed in ASDEX Upgrade (AUG) by combining a comprehensive set of pedestal measurements with both interpretive and predictive modelling. The experimentally determined ion heat diffusivities, ...

Effects of density gradients and fluctuations at the plasma edge on ECEI measurements at ASDEX Upgrade
(IOP Publishing, 2018)
Electron cyclotron emission imaging (ECEI) provides measurements of electron temperature (Te) and its fluctuations (δTe). However, when measuring at the plasma edge, in the steep gradient region, radiation transport effects ...

Qualification and implementation of line ratio spectroscopy on helium as plasma edge diagnostic at ASDEX Upgrade
(IOP Publishing, 2018)
A new thermal helium beam diagnostic has been implemented as plasma edge diagnostic at the ASDEX Upgrade (AUG) tokamak. The helium beam is built to measure the electron density ne and temperature Te simultaneously with ...

Velocity space resolved absolute measurement of fast ion losses induced by a tearing mode in the ASDEX Upgrade tokamak
(IOP Publishing, 2018)
Absolute flux of fast ion losses induced by tearing modes have been measured by means of fast ion loss detectors (FILD) for the first time in RF heated plasmas in the ASDEX Upgrade tokamak. Up to 30 MW m−2 of fast ion ...

Experimental conditions to suppress edge localised modes by magnetic perturbations in the ASDEX Upgrade tokamak
(IOP Publishing, 2018)
Access conditions for full suppression of edge localised modes (ELMs) by magnetic perturbations (MP) in low density high confinement mode (H-mode) plasmas are studied in the ASDEX Upgrade tokamak. The main empirical ...
