A tracking detector to study O(1 GeV) ? ? CC interactions

A novel spectrometer to search for sterile neutrino with a short baseline ?? beam was proposed. The detector includes a tracking system composed of planes of triangular shape scintillator strips (3.3 cm à- 1.7 cm ) coupled to Silicon PhotoMultipliers in analog mode readout. A spatial resolution of O(1 mm) is required for the determination of charge sign of muons produced in ?? CC interactions at few GeV energy scale. The tracking detector was tested with cosmic rays and particle beams at CERN PS. A spatial resolution ? 1.8 mm is achieved wih a detector based on cm size scintillator strips.
