The next generation of neutrino experiments requires measurements of absolute neutrino cross sections at the GeV scale with high precision (∼1%) presently limited by the uncertainties on neutrino flux. Monitoring the lepton production in the decay tunnel of neutrino beams is the most straightforward way to measure the neutrino flux at source. The ENUBET Collaboration develops novel technologies to monitor positrons from K + → νee +π0 decays on an event by event basis. This technique can achieve a precision in the νe flux below 1% and enable a new generation of cross section and short baseline experiments. In this paper, we present the achievements of the first year of the Project on beamline simulation, rate and dose assessment, detector prototyping and evaluation of the physics reach.
