At present, a gyrotron with high-order volume mode of TE31,11 mode has been developed to realize the output power up to 1.4 MW by reducing the thermal loading at the cavity.stable start-up of main mode and high efficiency oscillations in hard excitation region were achieved. In steady-state operation, operation of 1.0 MW with total efficiency of 46% for 300s was achieved. Over-1MW operation of 1.2 MW for 5s was achieved. In addition, this gyrotron has demonstrated for quad-frequency oscillations.","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":"The 6th International Workshop on Far-Infrared Technologies (IW-FIRT 2017)","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":"池田, 亮介"}],"nameIdentifiers":[{"nameIdentifier":"712075","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小田, 靖久"}],"nameIdentifiers":[{"nameIdentifier":"712076","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小林, 貴之"}],"nameIdentifiers":[{"nameIdentifier":"712077","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"梶原, 健"}],"nameIdentifiers":[{"nameIdentifier":"712078","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高橋, 幸司"}],"nameIdentifiers":[{"nameIdentifier":"712079","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森山, 伸一"}],"nameIdentifiers":[{"nameIdentifier":"712080","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"坂本, 慶司"}],"nameIdentifiers":[{"nameIdentifier":"712081","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"池田 亮介","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"712082","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小田 靖久","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"712083","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小林 貴之","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"712084","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"梶原 健","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"712085","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高橋 幸司","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"712086","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森山 伸一","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"712087","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"坂本 慶司","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"712088","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":"Development of ITER Gyrotron in QST","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Development of ITER Gyrotron in QST"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-04-26"},"publish_date":"2017-04-26","publish_status":"0","recid":"72297","relation_version_is_last":true,"title":["Development of ITER Gyrotron in QST"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:41:30.974032+00:00"}
