Abstract
The multi-channel HCN-polarimeter on TEXTOR-94 has been used to measure the plasma current density for a wide range of operation/confinement conditions. The characteristic features of the safety factor profiles in discharges with edge-radiation cooling and the application of different heating scenarios together with a strong impurity influx will be described. The stabilization of sawteeth and changes in the MHD behaviour of the plasma is related to modifications of the current density profile.
