This system aids the understanding of the tradeoff between lifetime and performance. To estimate the flux of the sputtered wall material, the number density of the sputtered iron was measured by laser absorption spectroscopy using an absorption line from ground atomic iron at 371.9935  nm. An ultravioletAlxInyGa(1–x–y)N diode laser was used as the probe. The estimated number density of iron was 1.1×1016  m–3, which is reasonable when compared with that measured by duration erosion tests. The relation between estimated erosion rate and magnetic flux density also agreed with that measured by duration erosion tests.","subitem_description_type":"Abstract"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"647","nameIdentifierScheme":"WEKO"}],"names":[{"name":"山本, 直嗣"}]}]},"item_2_publisher_20":{"attribute_name":"出版者","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/10.1063/1.2001630","subitem_relation_type_select":"DOI"}}]},"item_2_relation_25":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://rsi.aip.org/rsi/","subitem_relation_type_select":"URI"}}]},"item_2_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© Copyright 2005 American Institute of Physics"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","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_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"400","subitem_subject_scheme":"NDC"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Department of Advanced Energy Engineering Science, Kyushu University"},{"subitem_text_value":"Department of Aeronautics and Astronautics, The University of Tokyo"},{"subitem_text_value":"Department of Advanced Energy, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Yamamoto, Naoji"}],"nameIdentifiers":[{"nameIdentifier":"642","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yokota, Shigeru"}],"nameIdentifiers":[{"nameIdentifier":"643","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsui, Makoto"}],"nameIdentifiers":[{"nameIdentifier":"644","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Komurasaki, Kimiya"}],"nameIdentifiers":[{"nameIdentifier":"645","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Arakawa, Yoshihiro"}],"nameIdentifiers":[{"nameIdentifier":"646","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-05-30"}],"displaytype":"detail","filename":"RSI7608.pdf","filesize":[{"value":"119.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"RSI7608.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/127/files/RSI7608.pdf"},"version_id":"d987b0de-0e9d-4563-8f68-d1cdbc6424fc"}]},"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":"Measurement of erosion rate by absorption spectroscopy in a Hall thruster","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Measurement of erosion rate by absorption spectroscopy in a Hall thruster"}]},"item_type_id":"2","owner":"1","path":["11","17"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-08-15"},"publish_date":"2007-08-15","publish_status":"0","recid":"127","relation_version_is_last":true,"title":["Measurement of erosion rate by absorption spectroscopy in a Hall thruster"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:41:06.333644+00:00"}
