Beschreibungen/Notizen

• To help constrain the algorithms used in reconstructing high-energy muon events incident on the Sudbury Neutrino Observatory (SNO), a muon tracking system was installed. The system consisted of four planes of wire chambers, which were triggered by scintillator panels. The system was integrated with SNO's main data acquisition system and took data for a total of 95 live days. Using cosmic-ray events reconstructed in both the wire chambers and in SNO's water Cherenkov detector, the external muon tracking system was able to constrain the uncertainty on the muon direction to better than 0.6°. ► This paper describes a novel technique for calibrating tracking algorithms. ► The experimental accuracy achieved by this system was better than 1°. ► The principle behind the technique can be used in future underground experiments.
