The roles of inhomogeneities of radial electric field (Er) are known inevitable. In this mechanism, whether the first derivative of Er (shear) or the second derivative of Er (curvature) works most is decisive in determining the class of nontrivial solutions (which describe the barrier structure). Here we report the experimental identification of the essential role of the Er-curvature on the ETBs formation, for the first time, based on the high-spatiotemporal resolution spectroscopic measurement. While there is only a low correlation between ETBs formation and the Er-shear at the peak of normalized ion temperature gradient, we found the decisive importance of Er-curvature. The impact of the curvature is quantified, by comparing with theory. This is the fundamental basis to understand the structure of transport barriers in fusion plasmas.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Nature Publishing Group"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1038/srep30585","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://www.nature.com/articles/srep30585"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.nature.com/articles/srep30585","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2045-2322","subitem_source_identifier_type":"ISSN"}]},"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":"488622","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"神谷 健作","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"488623","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":"Experimental validation of nonuniformity effect of the radial electric field on the edge transport barrier formation in JT-60U H-mode plasmas","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Experimental validation of nonuniformity effect of the radial electric field on the edge transport barrier formation in JT-60U H-mode plasmas"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-03-19"},"publish_date":"2018-03-19","publish_status":"0","recid":"48592","relation_version_is_last":true,"title":["Experimental validation of nonuniformity effect of the radial electric field on the edge transport barrier formation in JT-60U H-mode plasmas"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:26:27.987472+00:00"}
