In order to investigate these features, it is important to measure the absolute electric and magnetic field intensities of the wave phenomena of interest in addition to the dynamic spectra. It is also essential to be able to determine the normal direction of the wave and the direction of the Poynting vectors for the phenomena. The VLF instruments cover a frequency range from a few Hz to 17.8kHz for electric and magnetic field components and are composed of the following subsystems : a wide band analyzer (WBA), mult-channel analyzers (MCA) Poynting flux analyzers (PFX), ELF frequency analyzers, and a vector impedance probe (VIP). The present report describes the characteristics of each subsystem briefly and introduces some preliminary results of the observations, such as an example of the wave normal direction of whistlers determined by PFX, a triggered emission generated from the Australian Omega signal, ion cyclotron emissions observed around the magnetic equatorial plane, and a typical vector impedance of the wire antenna.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0166924000","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":"京都大学工学部"},{"subitem_text_value":"京都大学工学部"},{"subitem_text_value":"金沢大学工学部"},{"subitem_text_value":"東京電機大学工学部"},{"subitem_text_value":"名古屋大学空電研究所"},{"subitem_text_value":"東京大学理学部"},{"subitem_text_value":"京都大学工学部"},{"subitem_text_value":"京都大学工学部"},{"subitem_text_value":"金沢大学工学部"},{"subitem_text_value":"京都大学工学部"},{"subitem_text_value":"京都大学工学部"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山本, 正幸"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"木村, 磐根"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"長野, 勇"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"橋本, 弘藏"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"岡田, 敏美"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"林, 幹治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"澤田, 晃"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"伊藤, 嘉彦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"軒内, 栄一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"岸, 洋司"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"笠原, 禎也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YAMAMOTO, Masayuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KIMURA, Iwane","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NAGANO, Isamu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HASHIMOTO, Kozo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OKADA, Toshimi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HAYASHI, Kanji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SAWADA, Akira","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ITO, Yoshihiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KENNAI, Eiichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KISHI, Yoji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KASAHARA, Yoshiya","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":"SA0166924.pdf","filesize":[{"value":"781.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0166924.pdf","url":"https://jaxa.repo.nii.ac.jp/record/33065/files/SA0166924.pdf"},"version_id":"b8123afd-1e4d-43d2-a32a-58bc5d9172a9"}]},"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 (EXOS-D) 搭載 VLF 装置による初期観測結果","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"あけぼの (EXOS-D) 搭載 VLF 装置による初期観測結果"}]},"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":"33065","relation_version_is_last":true,"title":["あけぼの (EXOS-D) 搭載 VLF 装置による初期観測結果"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:16:38.665393+00:00"}
