Description
In the future LBNF beamline, the systematic uncertainty of the neutrino flux at the proposed DUNE Near Detector is currently approximately 10%, which will be a limiting systematic for most detector-only measurements. The neutrino flux uncertainty is dominated by uncertainties in hadron production cross sections. We propose a new, compact experiment to measure total and double-differential hadron production cross sections across a range of relevant beam energies, beam particle types and nuclear targets. These measurements will reduce the neutrino flux uncertainty to better than 5%.
