  The EUROnu Super Beam work package has studied a neutrino beam based on SPL
at CERN and aimed at MEMPHYS, a large water Cherenkov detector, proposed for
the Laboratoire Souterrain de Modane (Fr\'ejus tunnel, France), with a baseline
of 130 km. The aim of this proposed experiment is to study the CP violation in
the neutrino sector.
  In the study reported here, we have developed the conceptual design of the
neutrino beam, especially the target and the magnetic focusing device. Indeed,
this beam present several unprecedented challenges, like the high primary
proton beam power (4 MW), the high repetition rate (50 Hz) and the low energy
of the protons (4.5 GeV). The design is completed by a study of all the main
component of the system, starting from the transport system to guide the beam
to the target up to the beam dump.
