Description
Wide-band neutrino beams can be divided into different energy and flavor spectra from using precision timing of neutrino-interaction events relative to the primary proton beam. This ‘stroboscopic’ approach applies equally for near and far detectors in an oscillation experiment and is complimentary to the off-axis approach to select a limited energy and flavor spectra. Timing-based energy and flavor discrimination produced by hadrons in-flight requires primary proton bunches of order 100 ps, with similar detector time resolution. We propose that this can be addressed using a superconducting cavity to rebunch the primary proton beam structure with a factor 10 higher RF frequency. This talk will describe the stroboscopic technique and simulations of its application to the LBNF beam and a future demonstration of the concept using the ANNIE detector on the Fermilab Booster Neutrino Beam.
