FACILITY (VDG,2FR CAD) CEA, DAM, DIF Van de Graaff accelerator 2344700100015
INC-SOURCE (P-T) 3H(p,n) 3He for 0.5-3 MeV neutrons 2344700100016
(D-D) 2H(2H,n) 3He for 3-7 MeV neutrons 2344700100017
(D-T) 3H(2H,n) 4He for 15-20 MeV neutrons. 2344700100018
DETECTOR (BGO) (Bi4Ge3O12) detector 3 in. diam x 6 in. length. 2344700100019
P/T ratio 83% at 1 MeV and 36% at 10 MeV. The energy 2344700100020
resolution close to 11% at 0.662 MeV. FWHM(%) = axE**b 2344700100021
with a = 346 +- 29 and b = 0.517 +- 0.017. 2344700100022
(FISCH) 2344700100023
SAMPLE 14 g of 238U, 7 cm diameter, 1.7 mg/cm2 areal density. 2344700100024
ANALYSIS (UNFLD) In order to unfold the spectra, the detector 2344700100025
response was simulated at different energies with the 2344700100026
PENELOPE Monte Carlo code. 2344700100027
METHOD (COINC) Coincidence between the fission events and 2344700100028
the gamma rays. 2344700100029
(TOF) The fission chamber signal was used as the event 2344700100030
trigger in the experiment. The gamma-ray detector was 2344700100031
placed 1 m away from the fission chamber. 2344700100032
CORRECTION Time-of-flight spectrum between the fission chamber 2344700100033
and the BGO detector was corrected for: 2344700100034
- background gamma-ray events 2344700100035
- high-energy prompt fission neutrons (detected via 2344700100036
inelastic scattering) 2344700100037

ERR-ANALYS (EN-ERR) Standard deviation of the incident neutrons 2344700100039
(ERR-S) Statistical uncertainties 2344700100040
(ERR-SYS) Systematic uncertainties result from 2344700100041
- the simulation of the detector response and the 2344700100042
efficiency calibration - 10-13% 2344700100043
- the number of fission - 3%. 2344700100044
