The diameter and mass of the 3268900100027 238U sample were 4.50 cm and 7.85 +- 0.10 microgram, 3268900100028 respectively. 3268900100029 DETECTOR (IOCH) A twin gridded ionization chamber were used as 3268900100030 alpha particle detector. The distances from the 3268900100031 cathode to grid, grid to anode, and anode to shield 3268900100032 were 61.0, 18.0 and 12.0 mm, respectively. 3268900100033 The working gas was Kr+2.89%CO2 and the pressure was 3268900100034 1.30 atm. 3268900100035 The high voltages for the cathode, grids and anodes 3268900100036 were -1900, 0 and +1200 V, respectively. 3268900100037 (BF3) A BF3 long counter was used as a neutron flux 3268900100038 monitor for each run normalization. 3268900100039 MONITOR (92-U-238(N,F),,SIG) 3268900100040 A 238U film sample was applied to determine the 3268900100041 absolute neutron flux. It was placed at the forward 3268900100042 direction of the 3rd position of the sample changer 3268900100043 for fission fragments measurement. 3268900100044 MONIT-REF (,,3,ENDF/B-VII.0,9237,2006) 3268900100045 INC-SOURCE (D-D) The deuterium gas cell was 2.0 cm in length and 3268900100046 0.9 cm in diameter with molybdenum film 5.0 micron 3268900100047 in thickness. 3268900100048 The deuterium gas pressure was 2.9-3.1 atm during 3268900100049 experiments. 3268900100050 The energy of accelerated deuteron beam before 3268900100051 entering the molybdenum film were 3.281, 2.455 and 3268900100052 1.790 MeV, respectively. 3268900100053 From Monte Carlo simulation, the corresponding energy 3268900100054 of produced neutrons on the sample were 6.0, 5.0 and 3268900100055 4.0 MeV, with the energy spreads of 0.12, 0.16 and 3268900100056 0.23 MeV. 3268900100057 PART-DET (A) 3268900100058 ERR-ANALYS (ERR-1,7.,11.)
