The shield was expected to prevent the detection of secondary species, which were recently found to be one of the vacuum facility effects. However, the shield seemed to have almost no effects on the ToF signals because the signal did not decrease to zero, and some particles were always detected as they had been detected without the shield. To examine the cause of this signal detection, the collector current was measured under the condition that the gate electrode completely blocked the ion beam. The results implied that the electrospray ion source also emitted some neutrals. The measurement system was reconstructed to detect ions using a high-speed amplifier to avoid neutral particle detection. Then, the results showed that the electrospray thruster was operating in the pure ion mode.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_2_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Acknowledgments \nThis work was partially supported by JSPS KAKENHI, Grant No. JP21H01530, the Canon Foundation, the Advisory Committee for Space Engineering of Japan Aerospace Exploration Agency, and JST FOREST Program Grant No. \nJPMJFR2129.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"International Symposium on Space Technology and Science","subitem_publisher_language":"en"}]},"item_2_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.57350/jesa.146","subitem_relation_type_select":"DOI"}}]},"item_2_rights_14":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Creative Commons Attribution 4.0 International","subitem_rights_language":"en","subitem_rights_resource":"https://creativecommons.org/licenses/by/4.0/"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"27581802","subitem_source_identifier_type":"EISSN"}]},"item_2_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Department of Mechanical Engineering, Materials Science, and Ocean Engineering, Yokohama National University","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"NAEMURA, Momoko","creatorNameLang":"en"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Division of Systems Research, Yokohama National University","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"TAKAO, Yoshinori","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"80552661","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=80552661"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-06-04"}],"displaytype":"detail","fileDate":[{"fileDateType":"Issued","fileDateValue":"2024-06-03"}],"filename":"2_146.pdf","filesize":[{"value":"707 KB"}],"format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://ynu.repo.nii.ac.jp/record/2001010/files/2_146.pdf"},"version_id":"fcf4185e-30bd-4560-8bc8-ed22a2ffa818"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Electric Propulsion, Electrospray Thruster, Ionic Liquid, Time-of-Flight","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":"Time-of-Flight Measurements of Ion Beam Compositions in Electrospray Thrusters","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Time-of-Flight Measurements of Ion Beam Compositions in Electrospray Thrusters","subitem_title_language":"en"}]},"item_type_id":"2","owner":"17","path":["496"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-06-04"},"publish_date":"2024-06-04","publish_status":"0","recid":"2001010","relation_version_is_last":true,"title":["Time-of-Flight Measurements of Ion Beam Compositions in Electrospray Thrusters"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2025-04-09T01:22:56.442899+00:00"}
