In order to develop the method, we measured the spectral emissivity of tungsten from 200 °C to 1900 °C in the wavelength range of 1.5 μm to 4.5 μm and evaluated temperature measurement error of the two-color method. The results indicate that temperature-dependent emissivity is a major factor in temperature measurement errors, which suggests that accurately measuring temperature by using the conventional two-color method would prove difficult. The new correction method uses two emissivity inputs at different temperature points, in contrast to the conventional method, which uses emissivity measured at a single temperature point. Using this new correction method with a suitable wavelength combination for the two-color method, temperature measurement error was reduced to less than 5% at 1900 °C.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.fusengdes.2021.112665","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://doi.org/10.1016/j.fusengdes.2021.112665","subitem_relation_type_select":"DOI"}}]},"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":"Tomohiko, Ushiki"}],"nameIdentifiers":[{"nameIdentifier":"996646","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ryota, Imazawa"}],"nameIdentifiers":[{"nameIdentifier":"996647","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hidetoshi, Murakami"}],"nameIdentifiers":[{"nameIdentifier":"996648","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kosuke, Shimizu"}],"nameIdentifiers":[{"nameIdentifier":"996649","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sugie, Tatsuo"}],"nameIdentifiers":[{"nameIdentifier":"996650","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takaki, Hatae"}],"nameIdentifiers":[{"nameIdentifier":"996651","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tomohiko, Ushiki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"996652","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ryota, Imazawa","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"996653","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hidetoshi, Murakami","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"996654","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kosuke, Shimizu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"996655","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tatsuo, Sugie","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"996656","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takaki, Hatae","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"996657","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":"Expanded two-color thermography considering temperature-dependent emissivity of tungsten for ITER divertor infrared thermography","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Expanded two-color thermography considering temperature-dependent emissivity of tungsten for ITER divertor infrared thermography"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-06-04"},"publish_date":"2021-06-04","publish_status":"0","recid":"82926","relation_version_is_last":true,"title":["Expanded two-color thermography considering temperature-dependent emissivity of tungsten for ITER divertor infrared thermography"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:56:20.244675+00:00"}
