It is found that in addition to turbulent particle transport, enhanced neoclassical particle transport due to a new synergy effect between turbulent and neoclassical transports makes a significant contribution to tracer impurity transport. Bursty excitation of the ITG mode generates non-ambipolar turbulent particle fluxes of electrons and bulk ions, leading to a fast growth of the radial electric field following the ambipolar condition. The divergence of ExB flows compresses up-down asymmetric density perturbations, which are subject to transport induced by the magnetic drift. The enhanced neoclassical particle transport depends on the ion mass because the magnitude of up-down asymmetric density perturbation is determined by a competition between the E_B compression effect and the return current given by the parallel streaming motion. This mechanism does not work for the temperature and, thus, selectively enhances only particle transport.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The American Institute of Physics"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1063/5.0027484","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://aip.scitation.org/doi/10.1063/5.0027484","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1070-664X","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":"Yasuhiro, Idomura"}],"nameIdentifiers":[{"nameIdentifier":"1008058","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Obrejan, Kevin"}],"nameIdentifiers":[{"nameIdentifier":"1008059","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Asahi, Yuichi"}],"nameIdentifiers":[{"nameIdentifier":"1008060","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mitsuru, Honda"}],"nameIdentifiers":[{"nameIdentifier":"1008061","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yasuhiro, Idomura","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1008062","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mitsuru, Honda","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1008063","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":"Dynamics of enhanced neoclassical particle transport of tracer impurity ions in ion temperature gradient driven turbulence","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Dynamics of enhanced neoclassical particle transport of tracer impurity ions in ion temperature gradient driven turbulence"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-02-09"},"publish_date":"2021-02-09","publish_status":"0","recid":"81797","relation_version_is_last":true,"title":["Dynamics of enhanced neoclassical particle transport of tracer impurity ions in ion temperature gradient driven turbulence"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:13:39.875195+00:00"}
