摘要：
The CERN to Gran Sasso neutrino facility (CNGS) is designed to study the nu(mu) -> nu(tau) oscillation with a high intensity neutrino beam sent to the ICARUS and OPERA long base-line experiments searching for nu(tau) appearance at LNGS. An ambitious and demanding project aimed to the protection of electronics against radiation has been devised and carried out in a very short time in 2008. Therefore the facility ran smoothly from June 18(th) to November 3(rd) 2008 delivering almost 2.0 . 10(19) proton on target. As a successive phase the CNGS facility could be addressed to the search of nu(mu) -> nu(e) subleading transitions driven by theta(13) mixing angle with a more intense off-axis neutrino beam. An increase of nearly an order of magnitude with respect to T2K expected sensitivity should be reached by exposing similar to 20 kt liquid Argon TPC detector shallow-depth all the Gran Sasso site.
