A plasma current sheet is created by exciting a plasma current along the magnetic neutral line of a two dimensional quadrupole magnetic field. A sudden anomalous increase of resistivity is observed which results in fast energy dissipation and strong plasma heating. The sudden increase of the plasma resistivity appears earlier and its magnitude increases as (i) the plasma density is decreased, (ii) the discharge plasma current is increased, or (iii) the external quadrupole magnetic field is increased. The electron temperature is measured from the absorption method of X-ray and the ion temperature from the electrostatic energy analyzer. When the sharp rise of the resistivity appears, the electron and ion temperature rise abruptly up to several keV range within O.5μ sec and about 10% of the initial energy stored in the capacitor for the plasma current excitation is converted into the ion thermal energy. This strong and .efficient ion heating cannot be explained by a simple classical process and the role of turbulent waves should be important.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0124431000","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":"愛媛大"}]},"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 Aeroautical Science University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Aeroautical Science University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Aeroautical Science University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"岡村, 昇一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大薮, 修義"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"河島, 信樹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"横田, 俊昭"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OKAMURA, S.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OYABU, N.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAWASHIMA, N.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YOKOTA, T.","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":"SA0124431.pdf","filesize":[{"value":"481.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0124431.pdf","url":"https://jaxa.repo.nii.ac.jp/record/31523/files/SA0124431.pdf"},"version_id":"dfcc0564-5767-4471-9a89-23c2a4914ae7"}]},"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":"太陽フレアおよびNeutral Sheetのモデル実験(IV)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"太陽フレアおよびNeutral Sheetのモデル実験(IV)"}]},"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":"31523","relation_version_is_last":true,"title":["太陽フレアおよびNeutral Sheetのモデル実験(IV)"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:57:38.285817+00:00"}
