Helium removal studies in I-mode discharges of TEXTOR
Intensive studies on helium removal with the pump limiter ALT-II have been performed for different discharge conditions. It has been shown that the figure of merit T(*)(He/Te) is sufficiently low for L-mode scaling discharge conditions even with strong radiative edge cooling. At the highest line averaged electron densities the effective residence time T(*)(He) is lowest. Results are presented on helium transport in I-mode discharges having the same improvement factor, with and without radiative edge cooling by neon.
