In contrast to the mu 10 whose ion beam current was saturated to 150 mA at higher microwave powers than 30 W, the mu 20 can generate 500 mA ion beam current with 100 W microwave power and 1100 - 1300 V acceleration voltage, yielding beam ion production cost (discharge power per unit beam current) of 200 W/A and thrust of 27 mN thanks to enlargement of the discharge chamber and moderate plasma density below cutoff. The mu 20 will be applied to deep space missions with larger delta-v and more massive spacecraft than Hayabusa.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064241005","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-08-013","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月惑星探査推進グループ"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"JAXA Space Exploration Center (JSPEC), Japan Aerospace Exploration Agency (JAXA)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"西山, 和孝"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nishiyama, Kazutaka","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":"64241005.pdf","filesize":[{"value":"586.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64241005.pdf","url":"https://jaxa.repo.nii.ac.jp/record/5322/files/64241005.pdf"},"version_id":"3eb16e47-a397-4899-a6b9-1356919a3904"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Microwave Discharge, Electron Cyclotron Resonance, Ion Engine","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"20cmマイクロ波放電式イオンエンジン","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"20cmマイクロ波放電式イオンエンジン"}]},"item_type_id":"5","owner":"1","path":["960","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"5322","relation_version_is_last":true,"title":["20cmマイクロ波放電式イオンエンジン"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:17:34.403096+00:00"}
