Measurement and simulations of high-energy neutrons through a various thickness of concrete and steel shields using activation detectors at CHARM and CSBF / Nakao, Noriaki (Tokyo Inst. Tech.) ; Sanami, Toshiya (KEK, Tsukuba) ; Kajimoto, Tsuyoshi (Hiroshima U.) ; Yashima, Hiroshi (Kyoto Sangyo U.) ; Froeschl, Robert (CERN) ; Bozzato, Davide (CERN) ; Iliopoulou, Elpida (CERN) ; Infantino, Angelo (CERN) ; Lee, Eunji (Kyushu U.) ; Oyama, Takahiro (KEK, Tsukuba) et al.
A shielding experiment using activation detectors was performed at the CERN High-energy AcceleRator Mixed-field (CHARM) facility and the CERN Shielding Benchmark Facility (CSBF). The protons (24 GeV/c) were bombarded into a 50-cm-thick copper target, and the released neutrons were transmitted through various shields located vertically upward from the target. [...]

Measurements of high-energy neutrons through shield penetration and maze streaming were performed at the Conseil Européen pour la Recherche Nucléaire (CERN) High-energy Accelerator Mixed-Field (CHARM) facility. The protons of 24 GeV/c were injected onto a 50-cm-thick copper target and the released neutrons were transmitted through shields and a maze in the facility. [...]

Measurements of secondary-particle emissions from copper target bombarded with 24-GeV/c protons / Oyama, Takahiro (KEK, Tsukuba) ; Sanami, Toshiya (KEK, Tsukuba) ; Yashima, Hiroshi (Kyoto U., KURRI) ; Hagiwara, Masayuki (KEK, Tsukuba) ; Nakao, Noriaki (Shimizu, Tokyo) ; Infantino, Angelo (CERN) ; Iliopoulou, Elpida (CERN) ; Froeschl, Robert (CERN) ; Roesler, Stefan (CERN) ; Kajimoto, Tsuyoshi (Hiroshima U.) et al.
To devise an activation technique for characterizing mixed radiation fields, secondary particles from a copper target irradiated by 24 GeV/c protons were measured at the CERN High-energy AcceleRator Mixed field facility (CHARM). Activation detector sets consisting of aluminum, niobium, indium, and bismuth, were placed at 30 cm from the target at angles of 15° to 160° with respect to the beam axis. [...]

Neutron energy spectrum measurement using an NE213 scintillator at CHARM / Kajimoto, Tsuyoshi (Hiroshima U. (main)) ; Sanami, Toshiya (KEK, Tsukuba) ; Nakao, Noriaki (Shimizu, Tokyo) ; Froeschl, Robert (CERN) ; Roesler, Stefan (CERN) ; Iliopoulou, Elpida (CERN ; Aristotle U., Thessaloniki) ; Infantino, Angelo (CERN) ; Brugger, Markus (CERN) ; Lee, Eunji (Kyushu U., Fukuoka (main)) ; Shigyo, Nobuhiro (Kyushu U., Fukuoka (main)) et al.
To establish a methodology for neutron spectrum measurement at the CERN High energy AcceleRator Mixed field facility (CHARM), neutron spectra were measured using an NE213 scintillator on top of the CHARM roof shielding where is the CERN Shielding Benchmark Facility (CSBF). The spectra were derived as fluences into the scintillator by the unfolding method using an iterative Bayesian algorithm. [...]
