We used LAS to obtain plasma profiles inside the μ1 miniature ion thruster developed by the Institute of Space and Astronautical Science of the Japan Aerospace Exploration Agency; this thruster is intended for installation on small spacecraft weighing up to 50 kg. It operates at low microwave power (1 W) and has been developed as a complete system, including a neutralizer. At present, the thrust efficiency of the μ1 thruster is not as high as that of standard ion thrusters and optimization is required. A detailed profile of plasma inside the discharge chamber is necessary for further improving performance. We developed an experimental LAS setup with spatial resolution of 0.1 mm for a modified μ1 thruster model. The number density distribution of neutral particles in a metastable state was measured and found to be about 10(exp17) m(exp-3).","subitem_description_type":"Other"}]},"item_7_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: PA1510002000","subitem_description_type":"Other"}]},"item_7_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本航空宇宙学会(JSASS)"}]},"item_7_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"The Japan Society for Aeronautical and Space Sciences (JSASS)"}]},"item_7_relation_25":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"info:doi/10.2322/tastj.12.Tb_31"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.2322/tastj.12.Tb_31","subitem_relation_type_select":"DOI"}}]},"item_7_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1884-0485","subitem_source_identifier_type":"ISSN"}]},"item_7_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Shizuoka University"},{"subitem_text_language":"en","subitem_text_value":"The University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency(JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Shizuoka University"},{"subitem_text_language":"en","subitem_text_value":"Shizuoka University"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Sugita, Yuto","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Koizumi, Hiroyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kuninaka, Hitoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamagiwa, Yoshiki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsui, Makoto","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Miniature Ion Thruster","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Plasma Measurement","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Laser Absorption Spectroscopy","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Number Density Measurement of Neutral Particles in a Miniature Microwave Discharge Ion Thruster","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Number Density Measurement of Neutral Particles in a Miniature Microwave Discharge Ion Thruster","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["1888"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-05-13"},"publish_date":"2015-05-13","publish_status":"0","recid":"22503","relation_version_is_last":true,"title":["Number Density Measurement of Neutral Particles in a Miniature Microwave Discharge Ion Thruster"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:20:04.035423+00:00"}
