Fast-Ion Transport Induced by Alfven Eigenmodes in ASDEX Upgrade

A comprehensive suite of diagnostics has allowed detailed measurements of the AE spatial structure and subsequent fast-ion transport. RSAEs and TAEs have been driven unstable by fast-ions from ICRH as well as NBI origin. In ICRF heated plasmas, diffusive and convective fast-ion losses induced by AEs have been characterized in fast-ion phase-space. While single RSAEs and TAEs eject resonant fast...

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...
