The plasma hole is a cylindrical density cavity, which is formed spontaneously in the center of the plasma. The steep density gradient between the hole plasma and the ambient plasma is sustained by a thin interfacial layer, the width of which is a few ion Larmor radii. Supersonic rotation is found over the large cross-sectional area of Ar plasma hole. The axial flow can also exceed ion sound speed. Spectral measurements revealed that the neutral density profile exhibits a hole structure as well as that in ion density, the diameter of which is much shorter than the mean free path of neutral particles.","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Japan Society of Plasma Science and Nuclear Fusion Research"}]},"item_2_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"Publisher version"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.jspf.or.jp/JPFRS/index_vol6-4.html","subitem_relation_type_select":"URI"}}]},"item_2_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"?2004 by The Japan Society of Plasma Science and Nuclear Fusion Research"}]},"item_2_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"YOSHIMURA,  Shinji","creatorNameLang":"en"}],"familyNames":[{}],"givenNames":[{}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OKAMOTO,  Atsushi"},{"creatorName":"OKAMOTO,  Atsushi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TANAKA,  Masayoshi Y."},{"creatorName":"TANAKA,  Masayoshi Y.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YOSHIMURA,  Shinji","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":"2016-03-23"}],"displaytype":"detail","filename":"301.pdf","filesize":[{"value":"787.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"301.pdf","url":"https://nifs-repository.repo.nii.ac.jp/record/461/files/301.pdf"},"version_id":"5a52da22-8abd-4dbc-ad00-565753ea3449"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"plasma hole","subitem_subject_scheme":"Other"},{"subitem_subject":"structure formation","subitem_subject_scheme":"Other"},{"subitem_subject":"macroscopic structure","subitem_subject_scheme":"Other"},{"subitem_subject":"vortex","subitem_subject_scheme":"Other"},{"subitem_subject":"supersonic ion flow","subitem_subject_scheme":"Other"},{"subitem_subject":"rotating plasma","subitem_subject_scheme":"Other"},{"subitem_subject":"ECR plasma","subitem_subject_scheme":"Other"},{"subitem_subject":"directional Langmuir probe","subitem_subject_scheme":"Other"},{"subitem_subject":"plasma hole","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"structure formation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"macroscopic structure","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"vortex","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"supersonic ion flow","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"rotating plasma","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ECR plasma","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"directional Langmuir probe","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Observation of Plasma Hole in an ECR Ar Plasma","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Observation of Plasma Hole in an ECR Ar Plasma"},{"subitem_title":"Observation of Plasma Hole in an ECR Ar Plasma","subitem_title_language":"en"}]},"item_type_id":"2","owner":"3","path":["7"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-02-05"},"publish_date":"2010-02-05","publish_status":"0","recid":"461","relation_version_is_last":true,"title":["Observation of Plasma Hole in an ECR Ar Plasma"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-31T04:58:56.970468+00:00"}
