Outline of Final Research Achievements |
In order to promote the research of nuclear reaction data and its use, we developed a system composed of accelerator neutron sources and a gamma-ray noise discriminating neutron detector. To measure the data of many kinds of nuclear fuel materials, we considered to place a small size X-band electron linac based neutron source inside Yayoi reactor, which is now under decommission in Tokai campus of the University of Tokyo. We designed the 30 MeV X-band linac neutron source and estimated its pulse width as 6.6 ns and its power as 1.3 E+11 n/s. We also designed portable neutron sources based on the X-band 3.95 MeV and 6 MeV linac sources. The pulse width was 4 us for both and the powers were 1.8 E+10 and 4.15 E+10 n/s, respectively. We also developed a detector which discriminate neutron from gamma noise. The detector was composed of Ce:LiCAF scintillator with wavelength shifter coating. We successfully demonstrated the measurement of the total cross sections of Neptunium and Uranium.
