This system has contributed to safe operation during two experimental campaigns without serious problems due to radiation (neutrons and gamma-rays). The cameras steadily functioned even in the plasma discharge with the maximum neutron emission rate in FY 2017, though some bright specks temporarily appeared on the images. The cameras have been installed in shield boxes which consist of lead boxes covered with 10% borated polyethylene blocks in all directions. For optimizing the design of the shield box, the radiation flux distribution was calculated by MCNP-6 code, which reveals the reduction of the radiation flux and the change of the energy spectra in the shield box. Thanks to the optimization, significant extension of the lifetime of the cameras has been realized. Investigation of the influence of the radiation on the CCD image sensor shows that the number of bright specks generally increases with the radiation flux to the camera, which also indicates that some bright specks disappear by the self-annealing process on the image sensor. This phenomenon also highly contributes to the further extension of the lifetime of the radiation resistant cameras.","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.15.2402039 ","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.15.2402039","subitem_relation_type_select":"DOI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(c) 2020 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":"12081"}]},"item_10001_text_25":{"attribute_name":"書誌的事項","attribute_value_mlt":[{"subitem_text_value":"the 28th International Toki Conference on Plasma and Fusion Research (ITC28)"}]},"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":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"SHOJI,  Mamoru"}],"familyNames":[{}],"givenNames":[{}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"LHD Experiment Group"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-06-13"}],"displaytype":"detail","filename":"12081_PFR.pdf","filesize":[{"value":"5.0 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"12081_PFR","url":"https://nifs-repository.repo.nii.ac.jp/record/11278/files/12081_PFR.pdf"},"version_id":"aaf9a3c3-b540-4fa5-8588-4c0b3cab83e4"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"radiation resistant camera","subitem_subject_scheme":"Other"},{"subitem_subject":"neutron","subitem_subject_scheme":"Other"},{"subitem_subject":"gamma-ray","subitem_subject_scheme":"Other"},{"subitem_subject":"CCD","subitem_subject_scheme":"Other"},{"subitem_subject":"deuterium plasma","subitem_subject_scheme":"Other"},{"subitem_subject":"LHD","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":"Radiation Resistant Camera System for Monitoring Deuterium Plasma Discharges in the Large Helical Device","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Radiation Resistant Camera System for Monitoring Deuterium Plasma Discharges in the Large Helical Device"}]},"item_type_id":"10001","owner":"20","path":["7"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-06-13"},"publish_date":"2022-06-13","publish_status":"0","recid":"11278","relation_version_is_last":true,"title":["Radiation Resistant Camera System for Monitoring Deuterium Plasma Discharges in the Large Helical Device"],"weko_creator_id":"20","weko_shared_id":-1},"updated":"2023-09-26T03:04:18.608185+00:00"}
