New method for the generation of neutrino beams at accelerators

The generation of neutrino beams at proton accelerators is a difficult scientific and engineering problem. To obtain narrow directional neutrino beams for experiments, intense extracted proton beams are used, secondary particles (pi and K mesons) are generated at an external target. Further, to obtain parallel beams of these neutrino parent particles, high-current electromagnetic lenses are used. In this work, a surprisingly simple method based on a crystal focusing device has been proposed to obtain neutrino beams. Neutrino fluxes are calculated in comparison with the traditional scheme.
