Energy spectra, intensity and composition of the CERN to Gran Sasso CNGS neutrino beam for nu_mu-->nu_tau and nu_mu-->nu_e oscillation searches are presented. The associated beam systematics, which is the major ingredient for the nu_mu-->nu_e search sensitivity, are obtained from the study of the previous CERN WANF.
