Two scientific PPBs were launched at Syowa Station, Antarctica by the 32nd and 31st Japanese Antarctic Research Exedition (JARE-32 and JARE-31) in December 1990 and in January 1991. Proton precession magnetometers (proton magnetometers) to measure geomagnetic field were carried with the purpose of research for the underground magnetic structure by magnetic anomalies and geomagnetic variation like a pulsation. New proton magnetometer system was developed that had a wide dynamical range and an automatic tuning system for PPB observation. Total intensity of the geomagnetic field were obtained by the ARGOS data transmition system every 30 seconds with an accuracy of 1nT during the flight of 22 days. The first balloon (PPB-1) had a perfect circumpolar trajectory and passed through the center of the Magnetic South Pole. We describe the new proton magnetometer system, preliminary results and future plan of magnetometry for PPB in this paper.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0167042000","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":"東海大学工学部"},{"subitem_text_value":"名古屋大学太陽地球環境研究所"},{"subitem_text_value":"国立極地研究所"},{"subitem_text_value":"東京大学理学部"},{"subitem_text_value":"宇宙科学研究所"},{"subitem_text_value":"宇宙科学研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"遠山, 文雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"藤井, 良一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"江尻, 全機"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"国分, 征"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"秋山, 弘光"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"矢島, 信之"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TOHYAMA, Fumio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"FUJII, Ryoichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"EJIRI, Masaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KOKUBUN, Susumu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"AKIYAMA, Hiromitsu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YAJIMA, Nobuyuki","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":"SA0167042.pdf","filesize":[{"value":"843.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0167042.pdf","url":"https://jaxa.repo.nii.ac.jp/record/33153/files/SA0167042.pdf"},"version_id":"2357597a-59d4-47dd-b9d9-f2a990acf23e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"プロトン磁力計","subitem_subject_scheme":"Other"},{"subitem_subject":"磁場測定","subitem_subject_scheme":"Other"},{"subitem_subject":"気球測定","subitem_subject_scheme":"Other"},{"subitem_subject":"磁気異常","subitem_subject_scheme":"Other"},{"subitem_subject":"南極磁場","subitem_subject_scheme":"Other"}]},"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":"プロトン磁力計を用いた南極周回気球 (PPB) による磁場測定実験","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"プロトン磁力計を用いた南極周回気球 (PPB) による磁場測定実験"}]},"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":"33153","relation_version_is_last":true,"title":["プロトン磁力計を用いた南極周回気球 (PPB) による磁場測定実験"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:14:17.133056+00:00"}
