We find that for a high-performance plasma, i.e. one with high plasma beta and steep pressure gradients, the turbulent outwards radial fluxes may be reduced by minimizing the elongation. We explain the results as a competition between the local magnetic shear and finite-Larmor-radius (FLR) stabilization. Electromagnetic studies indicate that kinetic ballooning modes are stabilized by increased shaping due to an increased sensitivity to FLR effects, relative to the ion-temperature-gradient instability. Nevertheless, at high enough β, increased elongation degrades the local magnetic shear stabilization that enables access to the region of ballooning second-stability.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1088/1741-4326/abf660","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/abf660","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":"Beeke, Oliver"}],"nameIdentifiers":[{"nameIdentifier":"1004089","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Barnes, Michael"}],"nameIdentifiers":[{"nameIdentifier":"1004090","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Romanelli, Michele"}],"nameIdentifiers":[{"nameIdentifier":"1004091","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakata, Motoki"}],"nameIdentifiers":[{"nameIdentifier":"1004092","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Maiko, Yoshida"}],"nameIdentifiers":[{"nameIdentifier":"1004093","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Maiko, Yoshida","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1004094","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 shaping on microstability in high-performance tokamak plasmas","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Impact of shaping on microstability in high-performance tokamak plasmas"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-04-12"},"publish_date":"2021-04-12","publish_status":"0","recid":"82718","relation_version_is_last":true,"title":["Impact of shaping on microstability in high-performance tokamak plasmas"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:28:20.107071+00:00"}
