In addition, we recognized a new role of the Er-shear as for the expansion of pedestal width, compensating an unfavorable effect of the Er-curvature having its sign dependence on the turbulence transport. We found a new interesting phenomenon of very slow out of phase oscillations between the Er and ion temperature gradient in the frequency range of 30-50 Hz, preceding the slow L-H transition, which can demonstrate a causality test of the ETB formation in association with the non-uniformity Er-effects. A critical condition for the Er-bifurcations is also discussed.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IOP"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1088/1361-6587/aa8a01","subitem_relation_type_select":"DOI"}}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"神谷, 健作"}],"nameIdentifiers":[{"nameIdentifier":"492386","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"伊藤, 公孝"}],"nameIdentifiers":[{"nameIdentifier":"492387","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"伊藤, 早苗"}],"nameIdentifiers":[{"nameIdentifier":"492388","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"居田, 克己"}],"nameIdentifiers":[{"nameIdentifier":"492389","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小林, 達也"}],"nameIdentifiers":[{"nameIdentifier":"492390","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"神谷 健作","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"492391","nameIdentifierScheme":"WEKO"}]}]},"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":"Role of electric field curvature in the formation of edge transport barrier in the JT-60U tokamak","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Role of electric field curvature in the formation of edge transport barrier in the JT-60U tokamak"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-05-08"},"publish_date":"2018-05-08","publish_status":"0","recid":"48875","relation_version_is_last":true,"title":["Role of electric field curvature in the formation of edge transport barrier in the JT-60U tokamak"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:23:22.286952+00:00"}
