The issues of designing the retro-reflector were (i) to achieve good thermal contact between the retro-reflector assembly and the FW and (ii) to accommodate the different thermal expansion of the retro-reflector made of tungsten and the FW made of stainless steel. In order to solve the issues, the CuCrZr filler was employed. A coupled mechanical-thermal analysis was carried out to confirm that the required contact pressure of 60 MPa persists during plasma operation. The highest predicted temperature of the retro-reflector was 673 °C, which is acceptable for tungsten. Electromagnetic analysis was carried out to confirm that the retro-reflector assembly will not move during plasma disruption. A maximum force of 3.06 kN is predicted on the retro-reflector during disruption and is much less than the static friction of 136 kN. In addition, the manufacturability of the retro-reflector assembly was successfully demonstrated. The roughness (Ra) and the flatness (root mean square) achieved for the mirror surface were 0.43 nm and 0.068 μm, respectively. The angle between the assembled mirrors was 90 ± 0.03°, better than the requirement of 90 ± 0.05°.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Science Direct"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.fusengdes.2020.111570","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.2020.111570","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":"Imazawa, Ryota"}],"nameIdentifiers":[{"nameIdentifier":"999259","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ono, Takehiro"}],"nameIdentifiers":[{"nameIdentifier":"999260","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Watts, Christopher"}],"nameIdentifiers":[{"nameIdentifier":"999261","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ishikawa, Masao"}],"nameIdentifiers":[{"nameIdentifier":"999262","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shimada, Takahiko"}],"nameIdentifiers":[{"nameIdentifier":"999263","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Itami, Kiyoshi"}],"nameIdentifiers":[{"nameIdentifier":"999264","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hatae, Takaki"}],"nameIdentifiers":[{"nameIdentifier":"999265","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ryota, Imazawa","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"999266","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ono, Takehiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"999267","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Masao, Ishikawa","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"999268","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takahiko, Shimada","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"999269","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kiyoshi, Itami","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"999270","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takaki, Hatae","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"999271","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":"Design and manufacturability demonstration of retro-reflectors of ITER poloidal polarimeter that are mounted in first wall panels","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Design and manufacturability demonstration of retro-reflectors of ITER poloidal polarimeter that are mounted in first wall panels"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-03-05"},"publish_date":"2020-03-05","publish_status":"0","recid":"79212","relation_version_is_last":true,"title":["Design and manufacturability demonstration of retro-reflectors of ITER poloidal polarimeter that are mounted in first wall panels"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:45:52.486036+00:00"}
