Extension of heating and pulse power capabilities at ASDEX upgrade

Pedestal Studies at ASDEX Upgrade

The ASDEX Upgrade suite of edge pedestal diagnostics has been significantly improved. A new edge ion temperature and toroidal velocity diagnostic as well as a novel diagnostic for radial electric fields (Er) have been added. The application of integrated data analysis in a probabilistic framework contributes substantially to the quality of Er and electron density profiles. The equilibrium recon...

The compact neutron spectrometer at ASDEX Upgrade.

The first neutron spectrometer of ASDEX Upgrade (AUG) was installed in November 2008. It is a compact neutron spectrometer (CNS) based on a BC501A liquid scintillating detector, which can simultaneously measure 2.45-MeV and 14-MeV neutrons emitted from deuterium (D) plasmas and γ radiation. The scintillating detector is coupled to a digital pulse shape discrimination data acquisition (DPSD) sys...

Real-Time Diagnostics at ASDEX Upgrade - Architecture and Operation

Diagnostics at ASDEX Upgrade have available a very large number of highly developed measuring channels. The prospect of making this wealth of information usable for plasma optimization led to the implementation of a number of diagnostics running data acquisition in real-time (RT). Ultimately, this development aims to achieve a network of intelligent diagnostics delivering analysed data for high...

2D electron cyclotron emission imaging at ASDEX Upgrade (invited).

The newly installed electron cyclotron emission imaging diagnostic on ASDEX Upgrade provides measurements of the 2D electron temperature dynamics with high spatial and temporal resolution. An overview of the technical and experimental properties of the system is presented. These properties are illustrated by the measurements of the edge localized mode and the reversed shear Alfvén eigenmode, sh...
