A neutron beam line has been constructed at the KEK-proton synchrotron. Neutrons have been produced by the disintegration reactions of deuterons in a 6 cm thick beryllium target. Deuteron beams of 2-6 GeV have provided neutron beams of 1-3 GeV. The neutron flux increases with the deuteron energy. The typical beam intensities obtained were 1 × 108, 2 × 108, and 3 × 108 neutrons per 1011 deuterons of 2, 4, and 6 GeV, respectively. The neutron-momentum width, Δp/p, was measured to be (4 ± 1)% in sigma at 1 GeV.
