Rectangular corrugations are used as slow-wave structures having surface waves with upper cutoff frequencies above 150 GHz (G-band). We examine how dispersion characteristics of surface waves are affected by accuracy in machining the corrugation amplitude, width, and period length. Of these, accuracy in the amplitude has the largest effect. Uniformly distributed annular electron beams are generated by a disk-type cold cathode and injected into the G-band BWO. G-band BWO operations in 137 - 173 GHz and above 173 GHz are achieved by changing the corrugation amplitude. The radiation patterns are fairly broad, and the estimated radiation power is at kW level.","subitem_description_type":"Abstract"}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Japan Society of Plasma Science and Nuclear Fusion Research"}]},"item_5_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1585/pfr.9.3406032","subitem_relation_type_select":"DOI"}}]},"item_5_relation_31":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.jstage.jst.go.jp/","subitem_relation_type_select":"URI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright(C)2014 一般社団法人プラズマ・核融合学会"},{"subitem_rights":"本文データは学協会の許諾に基づきJ-Stageから複製したものである"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12346675","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18806821","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Magori, Shota"}],"nameIdentifiers":[{"nameIdentifier":"37656","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ogura, Kazuo"}],"nameIdentifiers":[{"nameIdentifier":"37657","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Iwasaki, Takayuki"}],"nameIdentifiers":[{"nameIdentifier":"37658","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kojima, Junpei"}],"nameIdentifiers":[{"nameIdentifier":"37659","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yambe, Kiyoyuki"}],"nameIdentifiers":[{"nameIdentifier":"37660","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kubo, Shin"}],"nameIdentifiers":[{"nameIdentifier":"37661","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shimozuma, Takashi"}],"nameIdentifiers":[{"nameIdentifier":"37662","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kobayashi, Sakuji"}],"nameIdentifiers":[{"nameIdentifier":"37663","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Okada, Kohji"}],"nameIdentifiers":[{"nameIdentifier":"37664","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-07-29"}],"displaytype":"detail","filename":"9_3406032.pdf","filesize":[{"value":"890.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"9_3406032.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2532/files/9_3406032.pdf"},"version_id":"cf31b07f-3702-47e2-97fb-0d4d9b2adb97"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"oversized backward wave oscillator","subitem_subject_scheme":"Other"},{"subitem_subject":"weakly relativistic electron beam","subitem_subject_scheme":"Other"},{"subitem_subject":"cold cathode","subitem_subject_scheme":"Other"},{"subitem_subject":"slow-wave structure","subitem_subject_scheme":"Other"},{"subitem_subject":"rectangular corrugation","subitem_subject_scheme":"Other"},{"subitem_subject":"G-band","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Experimental Study on G-Band Oversized Backward Wave Oscillator Driven by Weakly Relativistic Electron Beam","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Experimental Study on G-Band Oversized Backward Wave Oscillator Driven by Weakly Relativistic Electron Beam"},{"subitem_title":"Experimental Study on G-Band Oversized Backward Wave Oscillator Driven by Weakly Relativistic Electron Beam","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","425"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-12-03"},"publish_date":"2014-12-03","publish_status":"0","recid":"2532","relation_version_is_last":true,"title":["Experimental Study on G-Band Oversized Backward Wave Oscillator Driven by Weakly Relativistic Electron Beam"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:35:41.034138+00:00"}
