Abstract

A tracking telescope employing six layers of Al drift tubes 50 cm long, with diameter d = 3 cm and wall thickness 500 mu m, has been built and successfully operated with a 40% Ar-60% iC(4)H(10) gas mixture at atmospheric pressure. The tube cells, with a 100 mu m thick Cu-Be wire strung along the axis, enter streamer mode operation at V = 4.6 kV and feature full efficiency and local resolution of less than or equal to 60 mu m.
