Abstract

Properties of the cold-neutron beam at the FUNSPIN facility of the SINQ neutron source of the Paul Scherrer Institute, Villigen, Switzerland were investigated. The measured flux density $|PHI$ = (2.46 +$_{-}$ 0.04) X 10$^{8}$ [cm$^{2}$ s mA]$^{-1}$ , the wavelength averaged mean polarization around the beam axis P$_{A}$ = (95.29 +$_{-}$ 0.04)% and the mean polarization over the full beam cross-section P = [89.75 +$_{-}$ 0.01 (stat) +$_{-}$ 1.0 (syst)]% are the main attributes of this powerful facility for fundamental particle physics experiments with slow neutrons.
