Agradecimentos: We thank G. Battistoni, A. Ferrari and P. Sala for providing us the tables of the neutrino cross-sections and A. Guglielmi for the details of the CNGS MC simulation. We also would like to thank D. Autiero for his help in accessing the information in the CERN database and for many discussions about the details of the beam characteristics and status during Run1 Ver menos

Abstract: The CERN Neutrino to Gran Sasso (CNGS) project aims to produce a high energy, wide band nu(mu) beam at CERN and send it toward the INFN Gran Sasso National Laboratory (LNGS), 732 km away. Its main goal is the observation of the nu(tau) appearance, through neutrino flavour oscillation. The beam started its operation in August 2006 for about 12 days: a total amount of 7.6 x 10(17) protons were delivered to the target. The LVD detector, installed in hall A of the LNGS and mainly dedicated to the study of supernova neutrinos, was fully operating during the whole CNGS running time. A total number of 569 events were detected in coincidence with the beam spill time. This is in good agreement with the expected number of events from Monte Carlo simulations Ver menos
