Water target at the ISIS spallation source: Neutrino and neutron fluxes

摘要

Effects arising from a water target placed in the ISIS spallation facility, used for both neutron and neutrino experiments, are considered. Calculations are presented for the neutrino flux from stopped muon(+) decay, and for the neutron fluxes from the ISIS moderators, for several versions of a water target situated upstream of the ISIS spallation source. Two possible configurations, that enhance the neutrino flux by 39-80% and produce relatively little reduction in neutron flux, are outlined. (orig.)
