THE LARGE-VOLUME DETECTOR (LVD) - A MULTIPURPOSE UNDERGROUND DETECTOR AT GRAN-SASSO

Abstract The large-volume detector (LVD) which will be installed in Hall A of the Gran Sasso Laboratory can be defined as an underground observatory devoted to neutrino astronomy and to the measurement of the penetrating components of cosmic rays. The detector consists of two major parts: the tracking system and the scintillator system. It is specifically designed to permit a multipurpose experiment allowing the detection of neutrino interaction inside the detector and the detection of omnidirectional mu-mesons and the measurement of their trajectories and direction of flight.
