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_2_text_34": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"subitem_text_value": "Journal Article"}]}, "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", "download_preview_message": "", "file_order": 0, "filename": "Koizumi_RSI_OnJournal.pdf", "filesize": [{"value": "151.2 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 151200.0, "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"], "permalink_uri": "http://hdl.handle.net/2261/3799", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2017-01-10"}, "publish_date": "2017-01-10", "publish_status": "0", "recid": "856", "relation": {}, "relation_version_is_last": true, "title": ["Development of Thrust Stand for Low Impulse Measurement from Microthrusters"], "weko_shared_id": null}
