Muon magnetized iron filter for beam dump experiment

Abstract

The design of a magnetized muon filter was elaborated for τ neutrino research in beam dump experiments. The parameters of the muon filter were optimized for 3000 GeV initial proton beam and 2 m detector radius installed at distance 300 m from the target. The main sources determining muon background on the detector were analyzed. It is shown that the filter provides a muon flux on the detector less than 10 −11 muon·proton −1.
