The large area Emulsion Tracker of the CHORUS experiment

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 m$^2$. Two layers were inst...

Descripción
Sumario: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 m$^2$. 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 $\mu$m, which keeps the momentum resolution of the spectrometer below 30\% up to momenta of about 15~GeV/$c$.
