Two ITER gyrotrons (#1 and #2) were manufactured. Performance tests of ITER gyrotrons have being carried out. In short pulse experiments (~ 1ms), the output power of 1 MW for both gyrotrons.  Long pulse experiments for one of the ITER gyrotron are underway. The output power of 1.06 MW for 200 s has been achieved. Here, the beam voltage, CPD voltage and beam current were 80.4 kV, 33.7 kV and 44.6 A, respectively. The total efficiency reached 50.7 % and the oscillation efficiency was 29.5 %. Full-power modulation of 5 kHz has being performed. Up to now, the 5 kHz modulation at 0.8 MW-level was achieved for 60 s.","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":"2018 US-EU-JAPAN RF HEATING TECHNOLOGY WORKSHOP","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":"Ikeda, Ryosuke"}],"nameIdentifiers":[{"nameIdentifier":"659865","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Oda, Yasuhisa"}],"nameIdentifiers":[{"nameIdentifier":"659866","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kajiwara, Ken"}],"nameIdentifiers":[{"nameIdentifier":"659867","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kobayashi, Takayuki"}],"nameIdentifiers":[{"nameIdentifier":"659868","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Terakado, Masayuki"}],"nameIdentifiers":[{"nameIdentifier":"659869","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takahashi, Koji"}],"nameIdentifiers":[{"nameIdentifier":"659870","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Moriyama, Shinichi"}],"nameIdentifiers":[{"nameIdentifier":"659871","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakamoto, Keishi"}],"nameIdentifiers":[{"nameIdentifier":"659872","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"池田 亮介","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"659873","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小田 靖久","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"659874","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"梶原 健","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"659875","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小林 貴之","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"659876","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"寺門 正之","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"659877","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高橋 幸司","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"659878","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森山 伸一","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"659879","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"坂本 慶司","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"659880","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":"Experiments of Performance Demonstration of ITER Gyrotron in QST","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Experiments of Performance Demonstration of ITER Gyrotron in QST"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-01-31"},"publish_date":"2019-01-31","publish_status":"0","recid":"67123","relation_version_is_last":true,"title":["Experiments of Performance Demonstration of ITER Gyrotron in QST"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:41:18.202431+00:00"}
