LASER INJECTED IMPURITY TRANSPORT IN OHMICALLY AND ICRF HEATED TFR PLASMAS
The transport of impurities into ohmic and ion- cyclotron radio-frequency (ICRF) heated plasmas has been studied by laser blow-off injection of vanadium. No difference has been found between the two experimental situations, in spite of the fact that degradation of the energy confinement time is observed in ICRF heated plasmas in the mode conversion regime. Additionally, simulation of the saw-tooth modulated He-like V**21+ resonance line has shown that the impurity transport parameters are not modified by the internal disruptions.
