It is very important to prevent microwave from going into the beam diode, since intense microwaves will harmfully affect beam generation. A weakly relativistic oversized BWO is demonstrated using a Bragg reflector at the input end of slow wave structure (SWS). The effect of the Bragg reflector on the BWO operation is examined, by changing the boundary condition at the SWS input end. The Bragg reflector improves the performance of the oversized BWO.", "subitem_description_type": "Abstract"}]}, "item_8_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Japan Society of Plasma Science and Nuclear Fusion Research"}]}, "item_8_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_8_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Ogura, Kazuo"}], "nameIdentifiers": [{"nameIdentifier": "169634", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Miyazawa, Yushi"}], "nameIdentifiers": [{"nameIdentifier": "169635", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Tanaka, Hidekazu"}], "nameIdentifiers": [{"nameIdentifier": "169636", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kiuchi, Yutaka"}], "nameIdentifiers": [{"nameIdentifier": "169637", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Aoyama, Satoshi"}], "nameIdentifiers": [{"nameIdentifier": "169638", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Sugawara, Akira"}], "nameIdentifiers": [{"nameIdentifier": "169639", "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": "2019-08-26"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "2_1041.pdf", "filesize": [{"value": "434.6 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 434600.0, "url": {"label": "2_1041.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/31093/files/2_1041.pdf"}, "version_id": "e7cc0b8a-2486-4296-8438-ee7e8f869062"}]}, "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": "Weakly Relativistic K-band Oversized Backward Wave Oscillator with Bragg Reflector at Input End of Slow Wave Structure", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Weakly Relativistic K-band Oversized Backward Wave Oscillator with Bragg Reflector at Input End of Slow Wave Structure"}, {"subitem_title": "Weakly Relativistic K-band Oversized Backward Wave Oscillator with Bragg Reflector at Input End of Slow Wave Structure", "subitem_title_language": "en"}]}, "item_type_id": "8", "owner": "1", "path": ["457", "436"], "permalink_uri": "http://hdl.handle.net/10191/21950", "pubdate": {"attribute_name": "公開日", "attribute_value": "2013-04-19"}, "publish_date": "2013-04-19", "publish_status": "0", "recid": "31093", "relation": {}, "relation_version_is_last": true, "title": ["Weakly Relativistic K-band Oversized Backward Wave Oscillator with Bragg Reflector at Input End of Slow Wave Structure"], "weko_shared_id": null}
