Outside a diagnostic port-plug, in the Interspace, a total dose of the orderof 1 MGy is expected through 20 years of ITER operation. In this study, gamma-ray irradiation experiments wereperformed up to 10 MGy. A high peak power laser beam, i.e. a pulse energy of 5 J and a pulse duration of∼4 ns,is needed for a Thomson scattering measurement in ITER. Laser-induced damage threshold (LIDT) of anti-re-flection (AR) and high-reflection (HR) coatings at the laser wavelengths after gamma-ray irradiation were in-vestigated. LIDT of AR coating for 0° injections was more likely higher for the irradiated samples at a wavelengthof 1064 nm. Regarding HR coatings, LIDT was not noticeably degraded by gamma-ray irradiation. Regardingpolarizers, no degradation of transmission and extinction ratio was observed at visible and near infrared wa-velength ranges when a wire-grid polarizer substrate is made of fused silica. Since a signal of ETS is almostlinearly polarized, a wire-grid polarizer enables to improve signal to noise ratio of electron temperature anddensity measurements by Thomson scattering in ITER.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.fusengdes.2020.111846","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.sciencedirect.com/science/article/pii/S092037962030394X","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0920-3796","subitem_source_identifier_type":"ISSN"}]},"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":"Eiichi, Yatsuka"}],"nameIdentifiers":[{"nameIdentifier":"1015415","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Torimoto, Kazuhiro"}],"nameIdentifiers":[{"nameIdentifier":"1015416","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Masao, Ishikawa"}],"nameIdentifiers":[{"nameIdentifier":"1015417","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takaki, Hatae"}],"nameIdentifiers":[{"nameIdentifier":"1015418","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Eiichi, Yatsuka","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1015419","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Torimoto, Kazuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1015420","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Masao, Ishikawa","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1015421","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takaki, Hatae","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1015422","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Gamma-ray irradiation effects on optical coatings and polarizers for edge Thomson scattering system in ITER","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Gamma-ray irradiation effects on optical coatings and polarizers for edge Thomson scattering system in ITER"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-03-22"},"publish_date":"2021-03-22","publish_status":"0","recid":"82391","relation_version_is_last":true,"title":["Gamma-ray irradiation effects on optical coatings and polarizers for edge Thomson scattering system in ITER"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T18:43:30.155815+00:00"}
