FACILITY (CCW,4RUSFEI) Pulsed neutron generator KG-0.3. 4149700100022
INC-SOURCE (D-T) Short (2.5ns) pulse of neutrons was generated 4149700100023
through T(d,n) reaction. Bombarding of solid titanium- 4149700100024
tritium target(11.mm diameter,0.8mm thickness,on copper4149700100025
backing,thin still tube of 0.55 thick as holder) with 4149700100026
pulsed beam of 280.keV deuterons. 4149700100027
METHOD (TOF) Flight Base 215 cm. 4149700100028
Measurement of background due to neutron scattering by 4149700100029
walls and apparatus in experimental room was made 4149700100030
without the sample. 4149700100031
SAMPLE Uranium sample as hollow cylinder of 4.52cm external 4149700100032
and 3.98cm internal diameters, 4.87cm height. 4149700100033
Sample from depleted U-238(U-235 content 0.2%), 326.8g 4149700100034
weight, placed at 14cm distance from Ti-T target at 4149700100035
78 degrees angle to deuteron beam direction. 4149700100036
DETECTOR (SCIN) NE-218 liquid scintillator in a glass vial of 4149700100037
10cm diameter, 5cm thickness, viewed by XP-2041 4149700100038
photomultiplier. Time resolution 3 ns, neutron 4149700100039
detection threshold about 0.3 MeV, gamma-ray 4149700100040
suppression factor about 5. 4149700100041
Detector was placed in lead shielding of 10 cm 4149700100042
thickness inside massive shield from mixture of 4149700100043
paraffin and lithium hydride, and in front - iron and 4149700100044
copper cones. All assembly was moved at angles from 4149700100045
30 to 150 degrees in step 30 degrees. 4149700100046
Detector efficiency was determined by two exp.methods:4149700100047
1.Neutron spectrum of spontaneous Cf-252 fission was 4149700100048
measured, known for 0.1-10.MeV energy range with 3% 4149700100049
accuracy (REL-REF). 4149700100050
(IOCH) Fast-response fission ionization chamber with 4149700100051
layer of Cf-252 was used. 4149700100052
2. Second method - relative to cross-section for 4149700100053
neutron scattering by hydrogen, known with accuracy 4149700100054
less 1.% (MONIT-REF). 4149700100055
Stilbene crystal of 10mm diameter and 40mm high was 4149700100056
used as scatterer, was mounted on photocathode of 4149700100057
FEU-30 photomultiplier. 4149700100058
(LONGC) Long counter was used to monitor neutron flux 4149700100059
from target. 4149700100060

attenuation in the sample was calculated by Monte 4149700100065
Carlo method, involving detailed modelling of 4149700100066
experiment: energy-angular distribution of source 4149700100067
neutrons, the dimensions and position of scatterer and4149700100068
neutron detector, using MCNP-4B code with ENDF-B6 and 4149700100069
ENDL-85 evaluated data libraries. 4149700100070
Elastic peak was subtracted at every scattering angle.4149700100071
Its energy shape was determined by measurement of the 4149700100072
