Description

The long-baseline neutrino oscillation experiment OPERA has been designed for the direct observation of ντ appearance in the CNGS νμ beam. The OPERA detector was located at the LNGS underground laboratory, with a distance of 730 km from the neutrino source at CERN. It was a hybrid apparatus built of about 150000 Emulsion Cloud Chamber modules providing micrometric resolution and Electronic Detector elements for online readout, interaction location, and the measurement of particle charge and momentum. CNGS beam data taking lasted from 2008 to 2012, and the detector has now been decommissioned. With the observation of 5 τ neutrino events, the experiment was able to report the discovery of νμ → ντ oscillations at a significance larger than 5σ. Combining all oscillation channels accessible at OPERA - including νe appearance and νμ disappearance - the neutrino oscillation analysis will conclude in 2017.
