It is a joint international research and development project involving Japan and Europe. The temperature distribution changes in recovery is investigated.\nThe quench recovery period is necessary to be confirmed. Generally, the maximum temperature drop of magnets is able to be confirmed by checking the thermometer attached to the outlet of the helium flow path. However, the maximum temperature of the JT-60SA central solenoid (CS) is not able to be measured during quench recovery. The flowing paths of CS is C-shaped and both of the outlets and the inlets of helium are on the outer periphery surface of the CS modules. Due to this C-shaped flowing path, heat exchanges between the inlet flow paths and the outlet flow paths. The CS outer periphery side becomes colder than the inner periphery side. The typical issue is the CS inside temperature is not able to be measured by the thermometers on the flowing paths. In this work, the CS temperature distribution changes during quench recovery is calculated and the period necessary for recovery is investigated.\nA CS module is composed of the 52 layers pancake coils. The 26 helium flowing paths are in a one module. The refrigerator supplies helium at 4.4 K to each flowing paths in nominal operation. In case of a quench, the refrigerator stops helium supply in order to shut out large heat load from the quenched magnet. The temperature distribution of the quenched CS will be smoothed by a heat conduction between each pancake coils while helium is stopped. Helium will be supplied again when the magnet pressure become low enough.\nThe temperature distribution changes are calculated by using the thermal fluid simulation codes.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The IEEE Council on Superconductivity"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1109/TASC.2020.2973128","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://ieeexplore.ieee.org/document/8993724","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1051-8223","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":"Fukui, Kazuma"}],"nameIdentifiers":[{"nameIdentifier":"999488","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Natsume, Kyohei"}],"nameIdentifiers":[{"nameIdentifier":"999489","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Murakami, Haruyuki"}],"nameIdentifiers":[{"nameIdentifier":"999490","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kizu, Kaname"}],"nameIdentifiers":[{"nameIdentifier":"999491","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Isono, Takaaki"}],"nameIdentifiers":[{"nameIdentifier":"999492","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kazuma, Fukui","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"999493","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kyohei, Natsume","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"999494","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Haruyuki, Murakami","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"999495","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kaname, Kizu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"999496","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takaaki, Isono","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"999497","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":"The Quench Recovery Analysis of the JT-60SA Superconducting Magnet","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The Quench Recovery Analysis of the JT-60SA Superconducting Magnet"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-03-10"},"publish_date":"2020-03-10","publish_status":"0","recid":"79291","relation_version_is_last":true,"title":["The Quench Recovery Analysis of the JT-60SA Superconducting Magnet"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:44:54.532879+00:00"}
