The chamber is 45 cm in inner diameter and 230 cm in length. Magnetic field of up to 400G can be applied along the chamber. A plasma is produced by a pulsed discharge between an oxide-coated cathode of 21 cm diameter and a grid or an anode. The width and the repetition of the pulse are 4msec and 4 Hz, respectively. A maximum discharge voltage is 110V and a current is 350A. The discharge is made in argon gas of pressure 5 × 10^<-5> ～ 5 × 10^<-4> Torr. The density and the temperature of electrons are &lsim; 10^<12> cm^<-3> and 1 ～ 4 eV, respectively. Propagation of whistler wave is studied also in an after glow plasma (the electron temperature ～0.1 eV) and dispersion relations are measured for some different plasma parameters. Equi-phase contours and amplitude profiles of whistler waves which are excited by a small antenna and which propagate in a non-uniform plasma are measured along and across the magnetic field. Directions of group and phase velocities with respect to the magnetic field are obtained and compared with a theory.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0125913000","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":"カリホルニア大学ロスアンジェルス校"}]},"item_9_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Aeronautical Science, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Aeronautical Science, University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中村, 良治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"野村, 雄二"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NAKAMURA, Yoshiharu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NOMURA, Yuzi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"STENZEL, R.L.","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":"SA0125913.pdf","filesize":[{"value":"742.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0125913.pdf","url":"https://jaxa.repo.nii.ac.jp/record/32587/files/SA0125913.pdf"},"version_id":"57a98785-23e0-46ea-a442-b3cd466d715d"}]},"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":"<論文>ホイッスラー波実験用磁化プラズマ装置","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"<論文>ホイッスラー波実験用磁化プラズマ装置"}]},"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":"32587","relation_version_is_last":true,"title":["<論文>ホイッスラー波実験用磁化プラズマ装置"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:28:38.203920+00:00"}
