FACILITY (VDGT,3CPRAEP) 13 MV Tandem accelerator S009400100009
SAMPLE The target with diameter 25 mm was composed of S009400100010
Be(99.2%), O(0.49%), Fe(0.115%), Al(0.056%), C(0.059%),S009400100011
Si(0.018%) and others(0.062%). It is necessary to take S009400100012
the target thickness of about 3 mm, to stop all S009400100013
deutrons with the highest incident energy (Ed=22 MeV). S009400100014
METHOD (TOF) In order to achieve a time interval of 1 S009400100015
microsecond corresponding to a neutron energy range S009400100016
from 0.5 to 30 MeV for the flight path of 6.76 m, S009400100017
beam pulse frequency of the accelerator must be S009400100018
chosen as 1 MHz. S009400100019
DETECTOR (SCIN) A stilbene scintillator 1 inch in thickness S009400100020
and diameter covered with a cylindrical aluminum S009400100021
container. It was positioned at 0 degree with respect S009400100022
to the beam direct ion. S009400100023
ERR-ANALYS No data given. In neutron spectrum measurements, the S009400100024
uncertainty of neutron detector efficiency is one of S009400100025
main error sources. In the energy range below 20 MeV, S009400100026
the efficiency curves of the neutron detector were S009400100027
determined by combining MC calculations using a S009400100028
standard code NEFF7 with experimental calibration S009400100029
measurement using a miniature 252Cf ionization S009400100030
chamber. In the energy range above 20 MeV, the S009400100031
efficiency were determined by measuring neutron S009400100032
angular distribution of T(d,n) reaction. S009400100033
CORRECTION Neutron flux attenuation in air, target and the S009400100034
heavily shielded detector and scattering neutrons S009400100035
material was calculated. S009400100036
ANALYSIS The fluence-averaged mean neutron energies of the S009400100037
neutron spectra are given as a function of the S009400100038
incident energy for several thresholds. The full S009400100039
neutron spectra were obtained by treating high energy S009400100040
En>1.8 MeV and low energy En<2.0 MeV portion S009400100041
respectively and then connecting them in a small S009400100042
overlap energy range from 1.8 and 2.0 MeV. S009400100043
