For the first time, it is shown that TEM-induced turbulent transport may remain unaffected by the steep fast ion pressure profile generated by the neutral beam injection. Unlike recent observations of ion temperature gradient (ITG)-\ninduced turbulent transport reductions due to fast ions, TEM-dominated systems could act differently in the presence of a significant fast ion population. The possible role of zonal flows as a saturation mechanism is analyzed, showing that their weak impact in the reported JT-60U scenario might lead to different behaviour of fast ions with respect to the ITG-dominated discharges. It is also shown that Alfvénic shear modes are destabilized at low wave numbers (n≈8). They are identified as drift Alfvén waves destabilized by ITG, which is a form of Alfvénic ITG instabilities. Deep numerical analysis provides the physical parameter range in which ITG-driven BAEs are stabilized. These results open the way to new possibilities of tailoring","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Institute of Physics"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1088/1741-4326/ab74a1","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://iopscience.iop.org/article/10.1088/1741-4326/ab74a1","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0029-5515","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":"Mazzi, S."}],"nameIdentifiers":[{"nameIdentifier":"931511","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zarzoso, D."}],"nameIdentifiers":[{"nameIdentifier":"931512","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Garcia, J."}],"nameIdentifiers":[{"nameIdentifier":"931513","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"T., Görler"}],"nameIdentifiers":[{"nameIdentifier":"931514","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Di Siena, A."}],"nameIdentifiers":[{"nameIdentifier":"931515","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Camenen, Y."}],"nameIdentifiers":[{"nameIdentifier":"931516","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Benkadda, S."}],"nameIdentifiers":[{"nameIdentifier":"931517","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshida, Maiko"}],"nameIdentifiers":[{"nameIdentifier":"931518","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hayashi, Nobuhiko"}],"nameIdentifiers":[{"nameIdentifier":"931519","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shinohara, Koji"}],"nameIdentifiers":[{"nameIdentifier":"931520","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Maiko, Yoshida","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"931521","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nobuhiko, Hayashi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"931522","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koji, Shinohara","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"931523","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":"Impact of fast ions on a trapped-electron-mode dominated plasma in a JT-60U hybrid scenario","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Impact of fast ions on a trapped-electron-mode dominated plasma in a JT-60U hybrid scenario"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-05-11"},"publish_date":"2020-05-11","publish_status":"0","recid":"79949","relation_version_is_last":true,"title":["Impact of fast ions on a trapped-electron-mode dominated plasma in a JT-60U hybrid scenario"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:38:00.078814+00:00"}
