Major achievements of the ITER gyrotron developments are as follows: (i) Manufacturing of 6 out of 8 sets of ITER gyrotrons was completed. Factory acceptance test (FAT) in QST has been progressed and 2 of 6 gyrotrons achieved required specifications such as 1 MW / 300 s / 50 %, 5 kHz modulation with ≥ 0.8 MW etc. The 50 mm diameter waveguide transmission-line and a matching optics unit (MOU) for ITER were newly introduced to perform the operation test at the same environment as ITER-site and excitation of HE11 mode purity of ≥ 95 % at the waveguide inlet was also successfully demonstrated, satisfying the requirement. (ii) Design of dual-frequency gyrotron, which is able to operate continuous wave of 1 MW power, was successfully completed.","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":"28th IAEA Fusion Energy Conference (FEC 2020)","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":"Ryosuke, Ikeda"}],"nameIdentifiers":[{"nameIdentifier":"1012564","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ken, Kajiwara"}],"nameIdentifiers":[{"nameIdentifier":"1012565","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakai, Taku"}],"nameIdentifiers":[{"nameIdentifier":"1012566","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Satoru, Yajima"}],"nameIdentifiers":[{"nameIdentifier":"1012567","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takayuki, Kobayashi"}],"nameIdentifiers":[{"nameIdentifier":"1012568","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koji, Takahashi"}],"nameIdentifiers":[{"nameIdentifier":"1012569","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shinichi, Moriyama"}],"nameIdentifiers":[{"nameIdentifier":"1012570","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Keishi, Sakamoto"}],"nameIdentifiers":[{"nameIdentifier":"1012571","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Darbos, C."}],"nameIdentifiers":[{"nameIdentifier":"1012572","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Henderson, M."}],"nameIdentifiers":[{"nameIdentifier":"1012573","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ryosuke, Ikeda","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1012574","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ken, Kajiwara","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1012575","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakai, Taku","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1012576","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Satoru, Yajima","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1012577","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takayuki, Kobayashi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1012578","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koji, Takahashi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1012579","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shinichi, Moriyama","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1012580","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Keishi, Sakamoto","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1012581","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":"Progress on Performance Tests of ITER-Gyrotrons and Design of Dual-Frequency Gyrotron for ITER Staged Operation Plan","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Progress on Performance Tests of ITER-Gyrotrons and Design of Dual-Frequency Gyrotron for ITER Staged Operation Plan"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-11-25"},"publish_date":"2021-11-25","publish_status":"0","recid":"83893","relation_version_is_last":true,"title":["Progress on Performance Tests of ITER-Gyrotrons and Design of Dual-Frequency Gyrotron for ITER Staged Operation Plan"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T18:55:29.294368+00:00"}
