Abstract

The OPERA experiment, designed to conclusively prove the existence of v(mu) -> v(tau) oscillations in the atmospheric sector, makes use of a massive lead-nuclear emulsion target to observe the appearance of v(tau)'s in the CNGS v(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 similar to 20cm(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.
