Abstract

On the ALT-II toroidal belt pump-limiter in TEXTOR thermographic and thermocouple measurements have been performed. The heat distribution on the blades shows some inhomogeneities which are attributed to different effects: (a) the leading edges at the ends of the blades are heated more than the rest, partly due to alignment errors, (b) poloidally there is an asymmetry because of differences in the directed particle fluxes, (c) the magnetic field ripple causes a modulation of the power flux and (d) the toroidal flatness of each tile generates non-uniformities toroidally. From the observed data the total energy flux to the limiter, the time resolved power flux to the limiter and the radial power decay length are derived.
