Abstract
A new type of tracking device using large area nuclear emulsion sheets was developed for the short baseline neutrino oscillation experiment, CERN-WA95/CHORUS. The emulsion tracker is made of three layers, each 25 mm thick including support, and covering an area of about 5 m2. Two layers were installed upstream and one downstream of the hexagonal magnet of the CHORUS hadron spectrometer. The achieved position resolution over the whole area is 25 μm, which keeps the momentum resolution of the spectrometer below 30% up to momenta of about 15 GeV/c.
