In this study, the MPD thruster doesn't have the coil for external magnetic field application but permanent magnet, Samarium cobalt. So, if magnetic Curie temperature is taken into consideration, the radiation-cooled thruster without cooling water can be designed. The manned Mars explorations which are a final objective of this study are missions for which a high specific impulse is needed. Using hydrogen, we could obtain a result of thrust 41.9 mN, specific impulse 2870 s, and thrust efficiency 12.5 %. We will perform performance improvement and heat analysis for development of a radiation-cooled thruster. And, to decrease cathode damage, we designed multi-hollow cathode. Using it, a new water-cooled thruster with changing anode geometry, distance between electrodes and magnet field strength was made.","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"},{"subitem_description":"形態: PDF","subitem_description_type":"Other"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"},{"subitem_description":"Physical characteristics: PDF","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0061856086","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: STEP-2012-003","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宇宙科学研究所(JAXA)(ISAS)"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"大阪工業大学"},{"subitem_text_value":"大阪工業大学"},{"subitem_text_value":"大阪工業大学"},{"subitem_text_value":"大阪工業大学"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Osaka Institute of Technology"},{"subitem_text_language":"en","subitem_text_value":"Osaka Institute of Technology"},{"subitem_text_language":"en","subitem_text_value":"Osaka Institute of Technology"},{"subitem_text_language":"en","subitem_text_value":"Osaka Institute of Technology"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"湖山, 典英"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"井端, 公紀"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"藤田, 雄也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田原, 弘一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Koyama, Norihide","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ibata, Hiroki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fujita, Katsuya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tahara, Hirokazu","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":"2020-01-20"}],"displaytype":"detail","filename":"61856086.pdf","filesize":[{"value":"972.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"61856086.pdf","url":"https://jaxa.repo.nii.ac.jp/record/16222/files/61856086.pdf"},"version_id":"4172865a-a1c1-4a40-966e-31a16e43eac0"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"MPD Thruster","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Steady-State","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Applied Magnetic Field","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Permanent Magnet","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Multi-Hollow Cathode","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":"永久磁石とマルチホローカソードを用いた輻射冷却式MPDスラスタの開発研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"永久磁石とマルチホローカソードを用いた輻射冷却式MPDスラスタの開発研究"}]},"item_type_id":"5","owner":"1","path":["1700","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"16222","relation_version_is_last":true,"title":["永久磁石とマルチホローカソードを用いた輻射冷却式MPDスラスタの開発研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T04:57:34.274622+00:00"}
