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 is located at the LNGS underground laboratory, with a distance of 730 km from the neutrino source at CERN. It is 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. While CNGS beam data taking lasted from 2008 to 2012, the neutrino oscillation analysis is still ongoing: With the observation of a 5th τ neutrino event in an enlarged data sample, the experiment was recently able to report the discovery of νμ → ντ oscillations at a significance larger than 5 σ.
