A solenoidal capture system for neutrino production

This paper describes the use of a high field solenoidal magnet to capture secondary pions from the production target. The captured pions subsequentially decay to produce the neutrino beam. A pion capture system using a high field solenoid magnet has been proposed for the muon collider. This technology would also be available for neutrino beam production. It is shown that a high field solenoid would produce a larger flux of neutrinos with energy, E_u<1.3 GeV, than a neutrino beam produced with a horn system. The ν_e, ν¯_e flux contamination in the solenoid neutrino beam is only 0.15%
