The onboard LEP (low energy particle) instrument has three different charged particle observation modes; 1) energy and pitch-angle distributions of auroral electrons and ions, 2) mass/charge analysis of positive ions, and 3) onboard detection of particle flux modulations in the HF and VLF ranges. In this report we describe the LEP instrumentation, and present some preliminary results from mode 1. Due to the initial orbital configuration, emphasis is placed on the dayside phenomena including the polar cusp. Unique examples of high particle activity in the polar cap, and the hot plasma distribution along the transpolar are also described. The observations in the cuspregion reveal intense but patchy electron fluxes accompanied by the keV-range ions with the characteristic energy/time/space dispersion. These data are interpreted as signatures of longitudinal and/or temporal fluctuations of the magnetosheath plasma injection into the polar cusp. The dayside is characterized by the frequent apperance of low-energy ion conics and beams accompanied by the intense low-energy electron precipitation. Finally It is noted that low-energy accelerated ions upwelling along the magnetic field line are observed in a very limited region around the dayside edge of the transpolar arc.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0166930000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0285-9920","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00354485","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"神戸大学工学部"},{"subitem_text_value":"通信総合研究所"},{"subitem_text_value":"京都大学理学部"},{"subitem_text_value":"通信総合研究所"},{"subitem_text_value":"国立極地研究所"},{"subitem_text_value":"国立極地研究所"},{"subitem_text_value":"国立極地研究所"},{"subitem_text_value":"神戸大学工学部"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"向井, 利典"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"賀谷, 信幸"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佐川, 永一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"平原, 聖文"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"三宅, 互"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小原, 隆博"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"宮岡, 宏"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"町田, 忍"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山岸, 久男"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"江尻, 全機"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松本, 治弥"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"伊藤, 富造"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MUKAI, T.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAYA, N.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SAGAWA, E.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HIRAHARA, M.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MIYAKE, W.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OBARA, T.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MIYAOKA, H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MACHIDA, S.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YAMAGISHI, H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"EJIRI, M.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MATSUMOTO, H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ITOH, T.","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-24"}],"displaytype":"detail","filename":"SA0166930.pdf","filesize":[{"value":"832.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0166930.pdf","url":"https://jaxa.repo.nii.ac.jp/record/33071/files/SA0166930.pdf"},"version_id":"9cf86fa5-e3ea-44fc-a223-85885f88f92b"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"「あけぼの」によるオーロラ粒子観測","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"「あけぼの」によるオーロラ粒子観測"}]},"item_type_id":"9","owner":"1","path":["1890","1912"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"33071","relation_version_is_last":true,"title":["「あけぼの」によるオーロラ粒子観測"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:16:26.489060+00:00"}
