Optimizing neutron moderators for a spallation-driven ultracold-neutron source at TRIUMF
W. Schreyer, C. A. Davis, S. Kawasaki +5
We report on our efforts to optimize the geometry of neutron moderators and converters for the TRIUMF UltraCold Advanced Neutron (TUCAN) source using MCNP simulations. It will use…
Measurement of the total neutron scattering cross section ratios of noble gases of natural isotopic composition using a pulsed neutron beam
Christopher C. Haddock, Masayuki Hiromoto, Katsuya Hirota +8
Precision measurements of slow neutron cross sections with atoms have several scientific applications. In particular the n-He s-wave scattering length is important to know bo…
Improved determination of thermal cross section of 14N(n,p)14C for the neutron lifetime measurement
R. Kitahara, K. Hirota, S. Ieki +21
In a neutron lifetime measurement at the Japan Proton Accelerator Complex, the neutron lifetime is calculated by the neutron decay rate and the incident neutron flux. The flux is o…
Neutron scattering cross section of diamond nanoparticle
Kenji Mishima, Toshiya Otomoa, Kazutaka Ikeda +1
Due to their large coherent scattering cross section, diamond nanoparticles (DNPs) are considered as a promising candidate material for a new neutron reflector. For investigation o…
Precise neutron lifetime experiment using pulsed neutron beams at J-PARC
Naoki Nagakura, Katsuya Hirota, Sei Ieki +22
The neutron lifetime is one of the basic parameters in the weak interaction, and is used for predicting the light element abundance in the early universe. Our group developed a new…
