A high-resolution tracking detector based on capillaries filled with liquid scintillator

Abstract Results are presented on tests in a 5 GeV/ c hadron beam of a high-resolution tracking detector constructed from 20 μm diameter glass capillaries filled with liquid scintillator. Details are given of the techniques used to eliminate noise in the readout system and to reduce cross-talk between capillaries. A spatial resolution of 15 μm is obtained.
