Major achievements are as follows: (i) The final design of ITER gyrotron was accomplished and manufacturing of 2 ITER gyrotrons was finished. Then their factory acceptance test (FAT) in QST has started with ITER relevant high voltage power supply configuration. The 1st ITER gyrotron has achieved 1 MW output power for 10 s pulse and 200 kW operation for 300 s which suggests thermally stable condition and sufficient cooling performance for 1 MW long pulse operation; (ii) The coupling function of gyrotron power into the transmission line (TL) waveguide was improved and calculation result of coupling efficiency was increased as high as 96.9% for the fundamental mode purity in waveguide inlet which could produce the sufficient LP01 mode purity in whole EC H&CD system. These results lead to success of ITER EC H&CD system construction toward first plasma.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"27th IAEA Fusion Energy Conference","subitem_description_type":"Other"}]},"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":"小田, 靖久"}],"nameIdentifiers":[{"nameIdentifier":"740175","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"池田, 亮介"}],"nameIdentifiers":[{"nameIdentifier":"740176","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中井, 拓"}],"nameIdentifiers":[{"nameIdentifier":"740177","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"梶原, 健"}],"nameIdentifiers":[{"nameIdentifier":"740178","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小林, 貴之"}],"nameIdentifiers":[{"nameIdentifier":"740179","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高橋, 幸司"}],"nameIdentifiers":[{"nameIdentifier":"740180","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"坂本, 慶司"}],"nameIdentifiers":[{"nameIdentifier":"740181","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森山, 伸一"}],"nameIdentifiers":[{"nameIdentifier":"740182","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Darbos, Caroline"}],"nameIdentifiers":[{"nameIdentifier":"740183","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Oda, Yasuhisa","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"740184","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ikeda, Ryosuke","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"740185","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakai, Taku","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"740186","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kajiwara, Ken","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"740187","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kobayashi, Takayuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"740188","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takahashi, Koji","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"740189","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakamoto, Keishi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"740190","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Moriyama, Shinichi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"740191","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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Completion of 1st ITER gyrotron manufacturing and 1 MW test result","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Completion of 1st ITER gyrotron manufacturing and 1 MW test result"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-21"},"publish_date":"2019-03-21","publish_status":"0","recid":"74883","relation_version_is_last":true,"title":["Completion of 1st ITER gyrotron manufacturing and 1 MW test result"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T07:33:12.927715+00:00"}
