The OPERA Experiment

OPERA(Oscillation Project with EmulsiontRacking Apparatus) is a new detector concept, iron(lead)emulsion for a long-baseline neutrino oscillation experiment. This experiment would perform an appearance search for υμ−υτ oscillation in the parameter region indicated by the atmospheric neutrino anomaly. OPERA can run at the Gran Sasso Laboratory in the proposed NGS (Neutrino to Gran Sasso) Beam fr...

Status of the OPERA experiment

The OPERA experiment in the underground Gran Sasso Laboratory (LNGS) has been designed to perform the first detection of neutrino oscillations in direct appearance mode in the muon to tau neutrino channel. The detector is hybrid, being made of an emulsion/lead target and of electronic detectors. It is placed in the CNGS neutrino beam 732 km away from the neutrino source. Runs with CNGS neutrino...

Performances of the OPERA RPCs

OPERA is a dedicated experiment for the observation of nm into nt oscillations through t appearance using a 730 km long baseline nm beam from CERN to the Gran Sasso underground laboratory. The detector is equipped with two spectrometers for muon identification and charm background rejection. Bakelite RPCs are used as inner trackers inside the iron magnet of the spectrometers. The experiment has...

Status of the OPERA experiment

The OPERA experiment has been designed to observe an unambiguous signal of νμ → ντ oscillation in the parameter region indicated by previous experiments in the atmospheric sector. It is based on the nuclear emulsion technique to directly observe among the neutrino interaction products the track of a τ lepton produced by a ντ appeared in a νμ beam. The OPERA detector is presently under construct...
