The Japan Aerospace Exploration Agency (JAXA) has performed the research and development of debris removal systems equipped with electrodynamic tethers and this study is a part of this effort. Our goal is to develop a propellant-free debris de-orbiting system by the combination of the field emission cathode and a bare tether. In the preliminary experiments, electron extraction tests of carbon nanotube cathodes made by thermal chemical vapor deposition and arc discharge process were conducted. The results showed that the carbon nanotube cathodes had sufficient emission capability for the electrodynamic tether application, although its endurance performance was not sufficient in our test. Further investigations on the durability improvement and the optimization of electrode configuration hate been started.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0049206075","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-05-001E","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構"},{"subitem_text_value":"宇宙航空研究開発機構"},{"subitem_text_value":"東芝"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency"},{"subitem_text_language":"en","subitem_text_value":"Toshiba Corporation"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"大川, 恭志"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"北村, 正治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"井関, 康"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okawa, Yasushi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kitamura, Shoji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Iseki, Yasushi","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":"2020-01-16"}],"displaytype":"detail","filename":"49206075.pdf","filesize":[{"value":"2.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"49206075.pdf","url":"https://jaxa.repo.nii.ac.jp/record/6390/files/49206075.pdf"},"version_id":"bb577637-c0db-40fa-86e0-ee81087c8645"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"エレクトロダイナミックテザーシステム","subitem_subject_scheme":"Other"},{"subitem_subject":"カーボンナノチューブ","subitem_subject_scheme":"Other"},{"subitem_subject":"電界放出陰極","subitem_subject_scheme":"Other"},{"subitem_subject":"宇宙機推進","subitem_subject_scheme":"Other"},{"subitem_subject":"宇宙デブリ","subitem_subject_scheme":"Other"},{"subitem_subject":"低高度地球周回軌道","subitem_subject_scheme":"Other"},{"subitem_subject":"電子放出","subitem_subject_scheme":"Other"},{"subitem_subject":"絶縁破壊","subitem_subject_scheme":"Other"},{"subitem_subject":"electrodynamic tether system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"carbon nanotube","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"field emission cathode","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"spacecraft propulsion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"space debris","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"low Earth orbit","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"electron emission","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"electric breakdown","subitem_subject_language":"en","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Preliminary testing of carbon-nanotube field emission cathodes for electrodynamic tethers","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Preliminary testing of carbon-nanotube field emission cathodes for electrodynamic tethers","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1066","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"6390","relation_version_is_last":true,"title":["Preliminary testing of carbon-nanotube field emission cathodes for electrodynamic tethers"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:56:38.820956+00:00"}
