The ENUBET project aims to reduce the flux-related systematics 1% on a narrow band neutrino beam through monitoring associated charged leptons in an instrumented decay tunnel. A key element of is design meson transfer line with conventional magnets that maximize yield K+ and π+ while minimizing total length outside region. In order limit particle rates tunnel instrumentation, high level collimation needed, thus allowing non-decayed mesons reach end At same time, fine-tuning shielding collimators required minimize any beam-induced background magnetic lattice optimized TRANSPORT. focusing from target performed static (quadrupole-based) system that, coupled slow proton extraction scheme, allows for significant pile-up reduction at instrumentation retaining large enough high-precision cross-section measurements 3 year time scale. Charge momentum selection 8.5GeV ± 10% bite by double dipole system. Shielding elements are full simulation facility Geant4. particular, powerful genetic algorithm used scan parameter space automatically find configuration minimizes halo preserving yield. This contribution will report results optimization studies final beamline, together dose estimation FLUKA simulation. alternative secondary beamline broad range (4, 6, 8.5 GeV/c) could enhance physics additionally discussed.
