A bstract In spring 2012 CERN provided two weeks of a short bunch proton beam dedicated to the neutrino velocity measurement over distance 730 km. The OPERA experiment at underground Gran Sasso Laboratory used an upgraded setup compared 2011 measurements, improving time accuracy. An independent timing system based on Resistive Plate Chambers was exploited providing accuracy ~1 ns. Neutrino and anti-neutrino contributions were separated using information by magnetic spectrometers. new...
