First experimental determination of ion flow velocities and temperatures in the ASDEX Upgrade divertor
For the analysis of ion dynamics (ie ion temperature and ion flow velocity distributions) in the divertor I of ASDEX Upgrade an optical spectroscopic system with high spectral, temporal and spatial resolution was brought into operation. Integrated along up to 74 lines of sight with different orientations to the magnetic field lines, emission spectra of atoms and ions were recorded with high resolution by an Echelle spectrometer and a 2-dimensional charge coupled device camera. With this setup, ion flow velocities and temperatures in a divertor plasma could be determined experimentally for the first time.
