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", "download_preview_message": "", "file_order": 0, "filename": "3_S1078.pdf", "filesize": [{"value": "618.5 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 618500.0, "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"], "permalink_uri": "http://hdl.handle.net/10191/21865", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2013-04-18"}, "publish_date": "2013-04-18", "publish_status": "0", "recid": "2541", "relation": {}, "relation_version_is_last": true, "title": ["Operation Characteristics of Microwave Sources Based on Slow-Wave Interaction in Rectangular Corrugation"], "weko_shared_id": -1}
