Edge and core Thomson scattering systems and their calibration on the ASDEX Upgrade tokamak
1Max-Planck Institut für Plasmaphysik, EURATOM Association, Garching, Germany. Bernd.Kurzan@ipp.mpg.de
Abstract:
A new 10 channel Thomson scattering (TS) system was installed on the ASDEX Upgrade tokamak to measure radial profiles of electron density and temperature at the plasma edge with high radial resolution. Together with the already existing TS system, which is now used for the core plasma, electron density and temperature profiles extending from the edge to the core are now obtained in a single discharge. The TS systems are relatively calibrated by an optical parametric oscillator.
