Abstract

The first results of the physical stage of the OPERA experiment in 2007, when observation of oscillations of gvμ into gvτ started, are discussed. Thirty eight events related to neutrino interactions in emulsion blocks (bricks) are found. The underground muon spectrum and the μ+/μ− ratio are obtained. The results of using detachable emulsion packs (changeable sheets) and accuracy of predictions of neutrino interaction vertices in emulsion layers are discussed. The results of the hardware and software upgrade of the automatic emulsion scanning system PAVIKOM are reported.
