L024200100011 FACILITY (LINAC,1CANOTC) National Research Council electron L024200100012 linear accelerator. L024200100013 INC-SOURCE (BRST,KINDT) L024200100014 DETECTOR (SCIN) The detector consisted of a 30-cm-diam, 8-cm- L024200100015 thick cylinder of NE102 plastic scintillator viewed L024200100016 by four photomultipliers. A neutron event was defined L024200100017 by a fast (20 nsec) coincidence between any two of L024200100018 them. L024200100019 SAMPLE Bremsstrahlung from a 0.05-cm Ta radiator, swept L024200100020 clean of electrons by a dump magnet, was used to L024200100021 irradiate a 4-liter, 12-cm-diam Dewar of liquid Ar L024200100022 placed 1 m from the radiator. L024200100023 METHOD (TOF) Conventional nanosecond time-of-flight methods L024200100024 with a resolution of 0.6-0.9 nsec/m (20 keV at a L024200100025 neutron energy of 1 MeV). Photoneutrons from the L024200100026 target entered an evacuated flight tube with internal L024200100027 collimation which allowed a proton recoil detector L024200100028 placed 31.2 m away to view a 15-cm-diam region of the L024200100029 target.
