Hydrogenous materials are mainly applied as a moderator material used in high-intense and small neutron sources because of good moderating characterization for neutrons. Scattering data including total cross sections of cold-thermal neutrons are important to characterize moderators. However, as some measurements are old, we have been continuously and systematically measuring the cross sections of hydrogenous materials since 2018 for a new neutron source development.
In this presentation, the measurements of methanol, benzene, and toluene carried out in 2019 and 2020 will be presented as a hydrogenous material. The measurements were performed at NOBORU and AMATERAS in MLF of J-PARC. The total cross sections were measured at NOBORU, and the scattering cross sections were measured at AMATERAS. The sample temperatures were 20, 100, 200, 300 K and temperatures near the melting point. The sample was contained in an aluminum cell. The time-of-flight method was used to measure the energy-dependent transmission of the sample. The scattering data was converted to the scattering cross section by a multiple energy chopping. Details will be preseted in the conference.
