It was intended to perform a new type of active experiment in space by applying a high voltage between the two payloads, as well as by injecting an electron beam from the tethered rocket system. An insulated conductive wire connecting the two payloads was deployed as long as 426m during the flight. An electron beam from 0.5 to 48mA at 1keV was injected from the mother payload. A voltage up to 500V was applied between the two payloads with and without the beam injection. This paper describes the initial results on the electrodynamic effects induced by the potential difference between the two payloads. The measurements of VxB electromotive force and voltage/current characteristics up to 500V have been explained by a model in which the ion current to the negatively-biased payload effectively limited the tether current. Two kinds of VLF waves were observed when the bias voltage was applied between the two payloads; narrow band emission at 2-4kHz and broad band emission up to 15kHz, depending on the applied voltage. The characteristic features of these emissions suggest that the lower hybrid instability (modified two stream instability) driven by the potential difference between the rocket and the ambient plasma was responsible for the wave generation. An extensive study on vehicle charging and associated wave generation during the beam injection from the tethered system will be reported in a separate paper.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0166846000","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":"ユタ州立大学"},{"subitem_text_value":"ユタ州立大学"},{"subitem_text_value":"スタンフォード大学"},{"subitem_text_value":"スタンフォード大学"},{"subitem_text_value":"ミシガン大学"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"佐々木, 進"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小山, 孝一郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"河島, 信樹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"平尾, 邦雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大林, 辰蔵"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SASAKI, SUSUMU","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OYAMA, KO-ICHIRO","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAWASHIMA, NOBUKI","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HIRAO, KUNIO","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OBAYASHI, TATSUZO","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"RAITT, W.
