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[1]. This technology would also be available for neutrino beam production. It will be shown that a high field solenoid would produce a larger flux of neutrinos with energy,E < 1:3GeV , than a neutrino beam produced with a horn system. The e; e flux contamination in the solenoid neutrino beam is only 0.15%.
