The OPERA experiment
H. Pessard (LAPP), the OPERA Collaboration
TL;DR
The OPERA experiment aims to detect tau neutrino appearance from long-distance neutrino oscillations using nuclear emulsion technology, with the detector under construction at Gran Sasso to analyze neutrino interactions from CERN.
Contribution
It introduces a novel long-baseline neutrino oscillation experiment employing nuclear emulsion techniques for tau neutrino detection.
Findings
Design and construction of the OPERA detector are underway.
Expected to measure nu_tau appearance with high precision.
Potential to search for nu_e appearance in the same setup.
Abstract
OPERA is a neutrino oscillation experiment designed to perform a nu\_tau appearance search at long distance in the future CNGS beam from CERN to Gran Sasso. It is based on the nuclear emulsion technique to distinguish among the neutrino interaction products the track of a tau produced by a nu\_tau and its decay tracks. The OPERA detector is presently under construction in the Gran Sasso underground laboratory, 730 km from CERN, and will receive its first neutrinos in 2006. The experimental technique is reviewed and the development of the project described. Foreseen performances in measuring nu\_tau appearance and also in searching for nu\_e appearance are discussed.
