The elevation angle of the rocket was 78° and the apogee was reached at 185km after 3min. 35s. The observations continued for about 7min. A Faraday cup and a glass-sealed Langmuir probe were used for the measurement. Fixed biases of ±6V were given to the grid of the cup for 0.25s alternately to measure saturated currents. A triangle sweep voltage with a period of 0.5s was given to the probe to measure the probe characteristic and its second derivative. Floating potential of the cup was also measured. The result shows that the currents at positive and negative biases are neary of the same order up to 85km while the current at the positive bias becomes larger according as the altitude increases. This indicates that the D layer consisits of a plasma with nearly the equal density of ions of both signs and with a small electron density whereas in E and F layers the electron density is much larger than the negative ion density.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0166977000","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":"理化学研究所"},{"subitem_text_value":"理化学研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"雨宮, 宏"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中村, 良治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"AMEMIYA, HIROSHI","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NAKAMURA, YOSHIHARU","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SHIGUEOKA, YOSHYUKI","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":"SA0166977.pdf","filesize":[{"value":"793.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0166977.pdf","url":"https://jaxa.repo.nii.ac.jp/record/33103/files/SA0166977.pdf"},"version_id":"faeac073-1a1a-44cc-9b65-8e3fc8ae716f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"D層","subitem_subject_scheme":"Other"},{"subitem_subject":"負イオン","subitem_subject_scheme":"Other"},{"subitem_subject":"ファラデーカップ","subitem_subject_scheme":"Other"},{"subitem_subject":"S-ロケット","subitem_subject_scheme":"Other"},{"subitem_subject":"冬","subitem_subject_scheme":"Other"},{"subitem_subject":"夜明け前","subitem_subject_scheme":"Other"},{"subitem_subject":"D-layer","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"negative ions","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Faraday cup","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"S-Rocket","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Winter","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Predawn","subitem_subject_language":"en","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":"S-310-20 号ロケットによる D 層の負イオン測定結果","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"S-310-20 号ロケットによる D 層の負イオン測定結果"}]},"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":"33103","relation_version_is_last":true,"title":["S-310-20 号ロケットによる D 層の負イオン測定結果"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:15:34.784307+00:00"}
