However, measurement of high-energy neutrons is still difficult because detector signals from neutrons are mixed with those from other components such as protons and heavy ions. Therefore, we try to develop a new monitoring system that can simply measure energetic cosmic neutrons in addition to protons, heavy ions and photons/electrons. For testing the feasibility, experiments of cosmic radiation measurements were performed in a jet aircraft using the newly developed instruments. It was verified that cosmic neutron with the energy greater than 10 MeV can be successfully detected separately from other components, though further study is necessary for determination of energy spectra of high-energy cosmic neutrons., 資料番号: AA0064297019},
