Abstract	The ENUBET project is aimed at designing and experimentally demonstrating the concept of monitored neutrino beams. These novel beams are enhanced by an instrumented decay tunnel, whose detectors reconstruct large-angle charged leptons produced in the tunnel and give a direct estimate of the neutrino flux at the source. These facilities are thus the ideal tool for high-precision neutrino cross-section measurements at the GeV scale because they offer superior control of beam systematics with respect to existing facilities. In this paper, we present the first end-to-end design of a monitored neutrino beam capable of monitoring lepton production at the single particle level. This goal is achieved by a new focusing system without magnetic horns, a 20 m normal-conducting transfer line for charge and momentum selection, and a 40 m tunnel instrumented with cost-effective particle detectors. Employing such a design, we show that percent precision in cross-section measurements can be achieved at the CERN SPS complex with existing neutrino detectors.

$The ENUBET beamline as implemented in G4Beamline, GEANT4 and FLUKA. Primary protons impinge on the target (not shown) located on the left of the figure; secondaries are sign and momentum selected by the transfer line and transported at the entrance of the instrumented decay tunnel (light green). From left to right: the quadrupole triplet (orange) and copper collimators (brown), double-bend momentum selector section composed of two dipoles (green), two quadrupoles, and one momentum copper collimator (brown), and the last quadrupole surrounded by two Inermet180 collimators (blue). The light-green cylinder represents the instrumented decay tunnel where a $K_{e3}$ decay is shown; the red track corresponds to the $\nu_{e}$ traveling towards the neutrino detector. The hadron dump that stops all particles but neutrinos is located at the tunnel exit. Non-interacting protons and forward particles travel inside the proton pipe (in gray) and are stopped by the proton dump (dark green). The neutrino detector considered in ENUBET (mass: 500 tons - not shown in the figure) is located 50 m far from the decay tunnel exit.$

$Kaon yields as a function of the graphite target length for a $400$~GeV/c proton beam. The figure of merit for the optimization is the number of kaons (10\% momentum bite) entering an ideal beamline with $\pm 20$~mrad angular acceptance in both planes placed $30$~cm after the target. Colors refer to different kaon's momenta while the line style identifies the target radius. The error bars (not plotted to ease the reading) are dominated by the FLUKA interaction modeling systematics and amounts to $\sim 20$\%.$ Show more plots
