Neutron dosimetry is very important for aircrews and astronauts, but neutron date have never been acquired satisfactorily yet, because of its difficulty. We have developed neutron detector to be able to measure neutron spectrum from a few MeV to above 100 MeV on board these crafts for radiation protection. This detector is requested to be safe and compact.\nThis detector consists on the liquid scintillator covered by the slow plastic scintillator. This liquid scintillator keeps high safety and has never attacked the plastic scintillator chemically for over 5 years. Short photomultiplier was developed to be on board crafts. Data acquisition system of pulse shape with fast ADC has been developed. The neutron detection system will be operated with a battery.\nExperiments for particle discrimination were done at NIRS-cyclotron and HIMAC. This detector can distinguish neutron events from gamma and proton events by using different pulse shapes. Especially, tail component of proton pulse shape produced by the slow plastic scintillator is different from that of neutron. New technique to discriminate neutron pulse shape from proton and gamma has been done by using fitting particle pulse shape.\nBy using this neutron detector and multi-spherical neutron detector, neutron spectra from thermal to over 100 MeV can be measured on board crafts, and this acquired spectra are necessary for radiation protection.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"11th International Congress of the International Radiation Protection Association","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Takada, Masashi"}],"nameIdentifiers":[{"nameIdentifier":"599772","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高田 真志","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"599773","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"High-energetic neutron spectrometer onboard aircraft and spacecraft","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"High-energetic neutron spectrometer onboard aircraft and spacecraft"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2004-06-03"},"publish_date":"2004-06-03","publish_status":"0","recid":"60400","relation_version_is_last":true,"title":["High-energetic neutron spectrometer onboard aircraft and spacecraft"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:54:10.283215+00:00"}
