Electrodes of the gun have been modified from the Pierce type gun because of the use of a directly heated cathode. Spatial density distributions of beam electrons emitted from the new gun have been measured in a large vacuum chamber, and characteristic curves of emission currents for some beam energies and cathode powers have been checked repeatedly for the next design. Finally the most suitable structure of the electrodes has been decided, which can make it possible to realize a low energy electron gun with a high power performance.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0166848000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0285-9920","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00354485","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"京都大学超高層電波研究センター"},{"subitem_text_value":"京都大学超高層電波研究センター"},{"subitem_text_value":"京都大学超高層電波研究センター"},{"subitem_text_value":"京都大学超高層電波研究センター"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"筒井, 稔"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大西, 嘉昭"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松本, 紘"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"木村, 磐根"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TSUTSUI, Minoru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ONISHI, Yoshiaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MATSUMOTO, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KIMURA, Iwane","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-24"}],"displaytype":"detail","filename":"SA0166848.pdf","filesize":[{"value":"666.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0166848.pdf","url":"https://jaxa.repo.nii.ac.jp/record/33009/files/SA0166848.pdf"},"version_id":"fb54bb69-ce4d-40e7-9c75-d992a7e8a4c9"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"GEOTAIL","subitem_subject_scheme":"Other"},{"subitem_subject":"ビームプラズマ相互信用実験","subitem_subject_scheme":"Other"},{"subitem_subject":"低エネルギー電子銃","subitem_subject_scheme":"Other"},{"subitem_subject":"放出電子ビームの特性測定試験","subitem_subject_scheme":"Other"},{"subitem_subject":"GEOTAIL","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Beam-plasma interaction experiment","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Electron gun.","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"地球磁気圏尾部観測衛星 (GEOTAIL) 搭載用低エネルギー電子ビーム装置の設計及び試作","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"地球磁気圏尾部観測衛星 (GEOTAIL) 搭載用低エネルギー電子ビーム装置の設計及び試作"}]},"item_type_id":"9","owner":"1","path":["1890","1912"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"33009","relation_version_is_last":true,"title":["地球磁気圏尾部観測衛星 (GEOTAIL) 搭載用低エネルギー電子ビーム装置の設計及び試作"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:18:13.393886+00:00"}
