CERN Neutrinos to Gran Sasso

The aim of the project was 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 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.

A proton beam was taken from the SPS at 400 GeV and is made to collide with a graphite target within the CNGS tunnel.

[1] Once the beam arrived at Gran Sasso, the OPERA and ICARUS experiments were used to detect the neutrinos.

[8] The preprint has been modified to account for these facts, and indeed the measurement of the neutrino speed, there reported, agrees with the velocity of the light.
