# Track reconstruction in the emulsion-lead target of the OPERA experiment using the ESS microscope

Abstract : The OPERA experiment, designed to conclusively prove the existence of $\rm \nu_\mu \to \nu_\tau$ oscillations in the atmospheric sector, makes use of a massive lead-nuclear emulsion target to observe the appearance of $\rm \nu_\tau$'s in the CNGS $\rm \nu_\mu$ beam. The location and analysis of the neutrino interactions in quasi real-time required the development of fast computer-controlled microscopes able to reconstruct particle tracks with sub-micron precision and high efficiency at a speed of 20 cm^2 / h. This paper describes the performance in particle track reconstruction of the European Scanning System, a novel automatic microscope for the measurement of emulsion films developed for OPERA.
