We present an optimization of the hadron focusing system for a low-energy high intensity conventional neutrino beam (super-beam) proposed on the basis of the HP-SPL at CERN with a beam power of 4 MW and an energy of 4.5 GeV. The far detector would be a 440 kton Water Cherenkov detector (MEMPHYS) located at a baseline of 130 km in the Fréjus site. The neutrino fluxes simulation relies on a new GEANT4 based simulation coupled with an optimization algorithm based on the maximization of the sensitivity limit on the θ 13 mixing angle. A new configuration adopting a multiple horn system with solid targets is proposed which improves the sensitivity to θ 13 and the CP violating phase δ CP.
