Stable operation of 170 GHz oscillation with higher total efficiency were achieved in ITER gyrotron with high-order volume mode of TE31,11 mode by introducing active anode voltage control and beam radius control to suppress adjacent counter-rotating modes. In long pulse operation, 1.0 MW/46 % for 300 s was achieved and 1.2 MW was obtained until 5 s. In multi-frequency oscillations, experiments of 203 GHz oscillation for a demo-reactor grade were started and the output power of 0.9 MW in short pulse and 0.42 MW for 5 s were demonstrated as preliminary results For lower frequencies, 1.0 MW/6 s at 137 GHz, and 1 MW/2 s and 0.93 MW/5 s at 104 GHz were also achieved. The ITER gyrotron having mega-watt-class power at four frequencies in wide range over 100 GHz was developed. In the JT-60SA gyrotron, oscillations of 1 MW/100 s at both 110 and 138 GHz had been already achieved. Enhancement of maximum power was progressed and 1.9 MW/1 s at 110 GHz, which is a world record power in non-coaxial type gyrotron has been achieved. And high-power oscillation at 138 GHz (1.3 MW/1.3 s) and 82 GHz (1 MW/1 s) have been demonstrated as a new record.","subitem_description_type":"Abstract"}]},"item_10003_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IAEA"}]},"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":"559832","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小林, 貴之"}],"nameIdentifiers":[{"nameIdentifier":"559833","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小田, 靖久"}],"nameIdentifiers":[{"nameIdentifier":"559834","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"梶原, 健"}],"nameIdentifiers":[{"nameIdentifier":"559835","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高橋, 幸司"}],"nameIdentifiers":[{"nameIdentifier":"559836","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森山, 伸一"}],"nameIdentifiers":[{"nameIdentifier":"559837","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"坂本, 慶司"}],"nameIdentifiers":[{"nameIdentifier":"559838","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"池田 亮介","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"559839","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小林 貴之","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"559840","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小田 靖久","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"559841","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"梶原 健","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"559842","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高橋 幸司","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"559843","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森山 伸一","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"559844","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"坂本 慶司","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"559845","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 paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Development of Multi-Frequency Mega-Watt Gyrotrons  for Fusion Devices in JAEA","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Development of Multi-Frequency Mega-Watt Gyrotrons  for Fusion Devices in JAEA"}]},"item_type_id":"10003","owner":"1","path":["2"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-04-26"},"publish_date":"2017-04-26","publish_status":"0","recid":"54758","relation_version_is_last":true,"title":["Development of Multi-Frequency Mega-Watt Gyrotrons  for Fusion Devices in JAEA"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T22:57:07.633745+00:00"}
