Because of their benefits of rapid response and directional properties to reduce restrictions on shielding, they are anticipated for installation in the Large Helical Device (LHD) of the National Institute for Fusion Science (NIFS). As described herein, the system design has been re-examined based on the results of recent experiments and simulations. Results show that fast neutrons with high energy of 14 MeV are attenuated by a self-shielding effect of scintillating fiber. Moreover, it has been demonstrated that the scintillation photons are attenuated in several centimeters before reaching the photon detector. The control of the photon transmission efficiency is important to enhance the directional property of the system. Along with reduced effects of the background gamma rays, adopting a thin scintillating fiber is effective. Further evaluation should be conducted to design a detector system considering the detecting efficiency, directional property, and gamma ray effect for application to an actual radiation field of the LHD.","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Japan Society of Plasma Science and Nuclear Fusion Research "}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1585/pfr.11.2405020 ","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"Publisher version"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1585/pfr.11.2405020","subitem_relation_type_select":"DOI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(c) 2016 The Japan Society of Plasma Science and Nuclear Fusion Research "}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12346675","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1880-6821","subitem_source_identifier_type":"ISSN"}]},"item_10001_text_23":{"attribute_name":"NAIS","attribute_value_mlt":[{"subitem_text_value":"10379"}]},"item_10001_text_25":{"attribute_name":"書誌的事項","attribute_value_mlt":[{"subitem_text_value":"the 25th International Toki Conference on Creating the Future – Innovative Science of Plasma and Fusion – "}]},"item_10001_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"TAKADA, Eiji"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"FUJISAKI, Akihiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NAKADA, Naoki"}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"ISOBE,  Mitsutaka"}],"familyNames":[{}],"givenNames":[{}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"OGAWA,  Kunihiro"}],"familyNames":[{}],"givenNames":[{}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NISHITANI, Takeo"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TOMITA,  Hideki"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-07-05"}],"displaytype":"detail","filename":"10379_PFR.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"10379_PFR","url":"https://nifs-repository.repo.nii.ac.jp/record/11413/files/10379_PFR.pdf"},"version_id":"160ce613-e3c0-4800-8df2-eba6c72276b1"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"neutron measurement","subitem_subject_scheme":"Other"},{"subitem_subject":"fast neutron directional detector","subitem_subject_scheme":"Other"},{"subitem_subject":"scintillating optical fiber","subitem_subject_scheme":"Other"},{"subitem_subject":"large helical device (LHD)","subitem_subject_scheme":"Other"},{"subitem_subject":"design","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Development of Fast-Neutron Directional Detector for Fusion Neutron Profile Monitor at LHD","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Development of Fast-Neutron Directional Detector for Fusion Neutron Profile Monitor at LHD"}]},"item_type_id":"10001","owner":"20","path":["7"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-07-05"},"publish_date":"2022-07-05","publish_status":"0","recid":"11413","relation_version_is_last":true,"title":["Development of Fast-Neutron Directional Detector for Fusion Neutron Profile Monitor at LHD"],"weko_creator_id":"20","weko_shared_id":-1},"updated":"2023-07-31T03:01:18.930331+00:00"}
