The beam voltage is weakly relativistic, which is less than 100 kV. A disk cathode can generate a uniformly distributed annular beam in the weakly relative region. Rectangular corrugation having the ratio of the corrugation width to the periodic length of 50 or 20% is used. Using the former, output powers of about 200kW are obtained at around 100 kV. For the latter, the effect of slow cyclotron resonance is observed in the low-energy region of around 30 kV. Output powers of slow cyclotron masers are in the range of a few hundred W. The operation mode of a slow cyclotron maser can be controlled between axisymmetric and nonaxisymmetric modes by changing the end condition of rectangular corrugation.","subitem_description_language":"en","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","subitem_publisher_language":"en"}]},"item_5_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1585/pfr.3.s1078","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/browse/pfr","subitem_relation_type_select":"URI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"一般社団法人プラズマ・核融合学会"}]},"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":"1880-6821","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Takamura, Yuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"37705","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kazahari, Yusuke","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"37706","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Oe, Hiroaki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"37707","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ogura, Kazuo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"37708","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sugawara, Akira","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"37709","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hirata, Masafumi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"37710","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":"3_S1078.pdf","filesize":[{"value":"618.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"3_S1078.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2541/files/3_S1078.pdf"},"version_id":"aceda74c-95f1-48c6-9c96-c98b91bbc989"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"slow-wave device","subitem_subject_scheme":"Other"},{"subitem_subject":"weakly relativistic region","subitem_subject_scheme":"Other"},{"subitem_subject":"disk cathode","subitem_subject_scheme":"Other"},{"subitem_subject":"annular electron beam","subitem_subject_scheme":"Other"},{"subitem_subject":"rectangular corrugation","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":"Operation Characteristics of Microwave Sources Based on Slow-Wave Interaction in Rectangular Corrugation","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Operation Characteristics of Microwave Sources Based on Slow-Wave Interaction in Rectangular Corrugation","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","425"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-04-18"},"publish_date":"2013-04-18","publish_status":"0","recid":"2541","relation_version_is_last":true,"title":["Operation Characteristics of Microwave Sources Based on Slow-Wave Interaction in Rectangular Corrugation"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-15T03:35:43.919895+00:00"}
