The electron gun has an ability to provide an electron beam with 5 KV, 300 mA (1.5 KW). The system is composed of tow sections, high voltage section for the electron gun operation and diagnostic instruments. The power to extract the electron beam for 80 ms every 5 sec. is provided from a capacitor bank charged by a high voltage power supply. Both acceleration voltage and beam current are varried systematically in three steps. The diagnostic includes Langmuir probe, a floating probe, three photomultipliers and VLF/HF receivers. The electron density and temperature in the ionosphere are measured by the Langmuir probe, and the charging of the rocket caused by the electron beam emission is measured by the floating probe. The visible emissions excited by the electron beam are observed by the photomultipiers with optical filters. The VLF and HF receivers are thrown away from the rocket (TAD, Throw Away Detector) and signals received by TAD are transmitted to the rocket by telemetry systems.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0124767000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学宇宙航空研究所"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0563-8100","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":"AN00161914","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学宇宙航空研究所"},{"subitem_text_value":"東京大学宇宙航空研究所"},{"subitem_text_value":"東京大学宇宙航空研究所"},{"subitem_text_value":"東京大学宇宙航空研究所"},{"subitem_text_value":"東京大学宇宙航空研究所"}]},"item_9_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"the Institute of Space and Aeronautical Science University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"the Institute of Space and Aeronautical Science University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"the Institute of Space and Aeronautical Science University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"the Institute of Space and Aeronautical Science University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"the Institute of Space and Aeronautical Science University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"矢守, 章"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"萩原, 通伸"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"金子, 修"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佐々木, 進"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"河島, 信樹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YAMORI, Akira","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HAGIWARA, Mitinobu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KANEKO, Osamu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SASAKI, Susumu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAWASHIMA, Nobuki","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":"2020-01-23"}],"displaytype":"detail","filename":"SA0124767.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0124767.pdf","url":"https://jaxa.repo.nii.ac.jp/record/31735/files/SA0124767.pdf"},"version_id":"b7bf0c64-6f1d-4ca5-8473-faf49547b823"}]},"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":"ロケット搭載用大出力電子銃装置","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ロケット搭載用大出力電子銃装置"}]},"item_type_id":"9","owner":"1","path":["1890","1910"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"31735","relation_version_is_last":true,"title":["ロケット搭載用大出力電子銃装置"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:52:09.148030+00:00"}
