Scalings and Plasma Profile Parameterisation of ASDEX High Density Ohmic Discharges

P. J. Mc Carthy, Kurt S. Riedel, O. Kardaun, H. Murmann et autres

High density ($.3 < \bar{n}/10^{20}{\rm m^{-3}} < .8$), low $q_a$ ($1.9} = .94(\pm.04){q_a}^{1.07\pm.04}$ in close agreement with the assumption of classical resistive equilibrium. In the inner half of the plasma, the inverse fall-off length for both temperature and density has a strong …

Edge and core Thomson scattering systems and their calibration on the ASDEX Upgrade tokamak

B. Kurzan, H. Murmann

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 …

Design and Calibration of a Polychromator for the Thomson Scattering at Wendelstein 7-X

S. Schmuck, A. Dinklage, R. Fischer, J. P. Knauer et autres

On Wendelstein 7-X, electron density and electron temperature profiles are planned to be measured by Thomson scattering. The specific system employs fiber bundles for the scattered light which is detected by means of a five-channel polychromator system. The detection system is assembled …

Plasma wall interaction and its implication in an all tungsten divertor tokamak

R. Neu, M. Balden, V. Bobkov, R. Dux et autres

ASDEX Upgrade has recently finished its transition towards an all-W divertor tokamak, by the exchange of the last remaining graphite tiles to W-coated ones. The plasma start-up was performed without prior boronization. It was found that the large He content in the …

Thomson scattering analysis of large scale fluctuations in the ASDEX Upgrade edge

B. Kurzan, L. D. Horton, H. Murmann, W. Suttrop et autres

Large scale fluctuations in between edge localized modes (ELMs) are the main source for the scatter in plasma edge H mode profiles of electron density and temperature, as measured by high precision, high resolution Thomson scattering. These large scale fluctuations are also …
