Rectangular corrugations are used as slow-wave structures (SWS) having surface waves with an upper cutoff frequency of approximately 100 GHz (W-band). Uniformly distributed annular electron beams are generated by a disk-type cold cathode and then are injected into the W-band oscillator. A longer SWS length causes the oscillator to function in both backward wave oscillator (BWO) and travelling wave tube (TWT) operations, and no meaningful oscillation occurs at the π-point or the Bragg condition. When the SWS length is short enough, oscillation occurs in all regions: BWO, π-point and TWT. The operations of the oscillator are strongly affected by the structure length. The maximum radiation power is estimated to be approximately 20 kW with the figure of merit of about 2 × 102 MW.GHz2.","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Japan Society of Plasma Science and Nuclear Fusion Research "}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1585/pfr.11.2406085 ","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"Publisher version"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1585/pfr.11.2406085 Details","subitem_relation_type_select":"DOI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(c) 2016 The Japan Society of Plasma Science and Nuclear Fusion Research "}]},"item_10001_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_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1880-6821","subitem_source_identifier_type":"ISSN"}]},"item_10001_text_23":{"attribute_name":"NAIS","attribute_value_mlt":[{"subitem_text_value":"10606"}]},"item_10001_text_25":{"attribute_name":"書誌的事項","attribute_value_mlt":[{"subitem_text_value":"the 25th International Toki Conference on Creating the Future – Innovative Science of Plasma and Fusion – "}]},"item_10001_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"SAN, Min Thu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OGURA, Kazuo"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YAMBE,  Kiyoyuki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ANNAKA, Yuta"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"GONG, Shaoyan"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAWAMURA, Jun"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MIURA, Takuro"}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"KUBO,  Shin"}],"familyNames":[{}],"givenNames":[{}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"SHIMOZUMA,  Takashi"}],"familyNames":[{}],"givenNames":[{}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KOBAYASHI,  Sakuji"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OKADA, Kohji "}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-07-01"}],"displaytype":"detail","filename":"10606_PFR.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"10606_PFR","url":"https://nifs-repository.repo.nii.ac.jp/record/11392/files/10606_PFR.pdf"},"version_id":"54030575-6496-46a9-bd6d-4d136bbcc916"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"surface wave","subitem_subject_scheme":"Other"},{"subitem_subject":"travelling wave tube operation","subitem_subject_scheme":"Other"},{"subitem_subject":"backward wave oscillator operation","subitem_subject_scheme":"Other"},{"subitem_subject":"π-point","subitem_subject_scheme":"Other"},{"subitem_subject":"W-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 W-Band (75 -
