INC-SPECT Neutron tangential beam from VVRM reactor was filtered 3070400100014
at fast-neutrons and gamma-rays using a special 3070400100015
collimator with quartz and bismuth polycrystal 3070400100016
filters. 3070400100017
METHOD (TOF) flight path =30.5 cm, channel width=0.487 nsec, 3070400100018
time resolution (FWHM of gamma-ray peak)=2.5 nsec3070400100019
DETECTOR (GLASD) Li glass detector (45 mm diam., 9.5 mm thick). 3070400100020
NE912 for fission neutrons, NE913 for gammas. 3070400100021
(FISCH) 1 atm Ar gas 3070400100022
MONITOR (98-CF-252(0,F),PR,NU/DE) 3070400100023
Effective neutron detector efficiency was determined 3070400100024
by measuring the Cf-252 fission neutron spectrum 3070400100025
assuming a Maxwellian distribution with T=1.42 MeV. 3070400100026
CORRECTION For neutron and gamma-ray detectors measurements were 3070400100027
carried out without add with a 12 cm long Cu shadow 3070400100028
cone, in order to determine the background due to 3070400100029
the scattering by the detector environment. 3070400100030
The relative contribution of the random coincidence 3070400100031
background - 130% at 30 keV, 40% at 60 keV, 20% 3070400100032
between 1 MeV and 2 MeV. 3070400100033
