The CERN Neutrinos to Gran Sasso (CNGS) project is a physics project of the European Organization for Nuclear Research (CERN). The aim of the project is to analyse the hypothesis of neutrino oscillation by directing a beam of neutrinos from CERN's facilities to the detector of the OPERA experiment at the Gran Sasso National Laboratory (LNGS), located in the Gran Sasso mountain in Italy. The CNGS facility is housed at the Meyrin site of CERN, at the Franco–Swiss border near Geneva, Switzerland. It uses the Super Proton Synchrotron (SPS) accelerator as a source of high-energy protons. ==History== Approval for the CNGS project was signed by the CERN Council in December 1999, with civil engineering on the project starting the following September. Construction of the tunnels and service caverns was completed in mid-2004, with equipment installation completed in summer 2005 and commissioning being carried out throughout spring 2006. The first proton beam was sent to the target on 11 July 2006, with the CNGS facility being approved for physics operations on 18 August 2006.
