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...
متن کاملThe 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...
متن کاملFast Ion Loss Diagnostic in ASDEX Upgrade
The confinement of fast particles is of crucial importance for next step fusion devices like ITER. Since fast ion losses might reduce the core heating and, in addition, cause untolerable first wall load, it is important to understand and possibly avoid them. Here, an integrated approach is presented for the analysis of neutral beam injection related fast ion losses in ASDEX Upgrade. It consists...
متن کاملIon orbit loss current in ASDEX Upgrade
The orbit loss current is calculated for the ASDEX Upgrade geometry using the 5D (3D in configuration space and 2D in velocity space) Monte Carlo code ASCOT. The balance between the obtained current and the analytical estimate of the return current shows an L–H transition for the normalized collision frequency ν∗i ≈ 1 as expected from analytic theory. The transition in ASDEX Upgrade, however, o...
متن کاملTitle: Adjoint Monte Carlo simulation of fusion product activation probe experiment in ASDEX Upgrade tokamak
The activation probe is a robust tool to measure flux of fusion products from a magnetically confined plasma. A carefully chosen solid sample is exposed to the flux, and the impinging ions transmute the material making it radioactive. Ultra-low level gamma-ray spectroscopy is used post mortem to measure the activity and, thus, the number of fusion products. This contribution presents the numeri...
