The impulse of LP-PPT ranged from 20 to 80 mNs. The diode laser microthruster, which is a new type of microthruster, produces much lower impulse range of 1\u201310 mNs for about 1 s. The mechanical noise induced from the background vibrations becomes a crucial problem for precise estimate of thrust particularly in low impulse measurements. A data analysis method to reduce the effect of mechanical noise is proposed by introducing an additional term in a fitting function. It was verified that the analysis method used in our experimental conditions reduced variance caused by noise down to one-third that of a normal fitting method. The accuracy of the thrust stand is 2.1 mNs in the case of the LP-PPT and 0.7 mNs in the case of the diode laser microthruster.","subitem_description_type":"Abstract"}]},"item_2_full_name_3":{"attribute_name":"\u8457\u8005\u5225\u540d","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"3303","nameIdentifierScheme":"WEKO"}],"names":[{"name":"\u5c0f\u6cc9, \u5b8f\u4e4b"}]},{"nameIdentifiers":[{"nameIdentifier":"3304","nameIdentifierScheme":"WEKO"}],"names":[{"name":"\u5c0f\u7d2b, \u516c\u4e5f"}]},{"nameIdentifiers":[{"nameIdentifier":"3305","nameIdentifierScheme":"WEKO"}],"names":[{"name":"\u8352\u5ddd, \u7fa9\u535a"}]}]},"item_2_publisher_20":{"attribute_name":"\u51fa\u7248\u8005","attribute_value_mlt":[{"subitem_publisher":"American Institute of Physics"}]},"item_2_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1063/1.1790568","subitem_relation_type_select":"DOI"}}]},"item_2_relation_25":{"attribute_name":"\u95a2\u4fc2URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://rsi.aip.org/rsi/","subitem_relation_type_select":"URI"}}]},"item_2_relation_26":{"attribute_name":"\u7570\u7248\u3067\u3042\u308b","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1063/1.1790568","subitem_relation_type_select":"URI"}}]},"item_2_rights_12":{"attribute_name":"\u6a29\u5229","attribute_value_mlt":[{"subitem_rights":"\u00a9 Copyright 2004 American Institute of Physics"}]},"item_2_source_id_10":{"attribute_name":"\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00817730","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00346748","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"\u8457\u8005","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Koizumi, Hiroyuki"}],"nameIdentifiers":[{"nameIdentifier":"3300","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Komurasaki, Kimiya"}],"nameIdentifiers":[{"nameIdentifier":"3301","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Arakawa, Yoshihiro"}],"nameIdentifiers":[{"nameIdentifier":"3302","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"\u30d5\u30a1\u30a4\u30eb\u60c5\u5831","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-05-30"}],"displaytype":"detail","filename":"Koizumi_RSI_OnJournal.pdf","filesize":[{"value":"151.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Koizumi_RSI_OnJournal.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/856/files/Koizumi_RSI_OnJournal.pdf"},"version_id":"29449fb8-583d-4cfc-a025-cfa8c4caafb9"}]},"item_keyword":{"attribute_name":"\u30ad\u30fc\u30ef\u30fc\u30c9","attribute_value_mlt":[{"subitem_subject":"Thrust stand","subitem_subject_scheme":"Other"},{"subitem_subject":"Microthruster","subitem_subject_scheme":"Other"},{"subitem_subject":"Low impulse measurement","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"\u8a00\u8a9e","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"\u8cc7\u6e90\u30bf\u30a4\u30d7","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Development of Thrust Stand for Low Impulse Measurement from Microthrusters","item_titles":{"attribute_name":"\u30bf\u30a4\u30c8\u30eb","attribute_value_mlt":[{"subitem_title":"Development of Thrust Stand for Low Impulse Measurement from Microthrusters"}]},"item_type_id":"2","owner":"1","path":["9/10/11","6/16/17"],"pubdate":{"attribute_name":"\u516c\u958b\u65e5","attribute_value":"2017-01-10"},"publish_date":"2017-01-10","publish_status":"0","recid":"856","relation_version_is_last":true,"title":["Development of Thrust Stand for Low Impulse Measurement from Microthrusters"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2021-03-02T08:42:17.414268+00:00"}
