The impact of Te/Ti on plasma transport and confinement is a critical issue for ITER and DEMO, where electron heating by alpha particles will be dominant. In the new experiments in DIII-D negative magnetic shear (NS) discharges, the Ti profile was maintained as Te/Ti increased through electron cyclotron range of frequency (ECRF) heating, while in positive magnetic shear (PS) plasmas, a large reduction in Ti was observed at increased Te/Ti. The different transport behavior has been explained by the turbulence measurements and GK simulations; the increase in Te/Ti had less impact on broadband turbulent fluctuations in the NS plasmas compared with that in the PS plasmas. The difference reflects changes in thermal energy confinement; the ion thermal diffusivity remained constant in the NS plasma but increased in the PS plasma when ECRF was applied. The reduced confinement degradation at high Te/Ti with NS has been commonly observed in DIII-D and JT-60U.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"26th IAEA Fusion Energy Conference","subitem_description_type":"Other"}]},"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":"Yoshida, Maiko"}],"nameIdentifiers":[{"nameIdentifier":"651104","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"R., McKee G."}],"nameIdentifiers":[{"nameIdentifier":"651105","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Murakami, M."}],"nameIdentifiers":[{"nameIdentifier":"651106","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"M., Collins C."}],"nameIdentifiers":[{"nameIdentifier":"651107","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"M., Davis E."}],"nameIdentifiers":[{"nameIdentifier":"651108","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"R., Ferron J."}],"nameIdentifiers":[{"nameIdentifier":"651109","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"M., Garofalo A."}],"nameIdentifiers":[{"nameIdentifier":"651110","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"A., Grierson B."}],"nameIdentifiers":[{"nameIdentifier":"651111","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"T., Holcomb C."}],"nameIdentifiers":[{"nameIdentifier":"651112","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Marinoni, A."}],"nameIdentifiers":[{"nameIdentifier":"651113","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakata, M."}],"nameIdentifiers":[{"nameIdentifier":"651114","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ono, M."}],"nameIdentifiers":[{"nameIdentifier":"651115","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"C., Petty C."}],"nameIdentifiers":[{"nameIdentifier":"651116","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"L., Rhodes T."}],"nameIdentifiers":[{"nameIdentifier":"651117","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Schmitz, L."}],"nameIdentifiers":[{"nameIdentifier":"651118","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"M., Solomon W."}],"nameIdentifiers":[{"nameIdentifier":"651119","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sung, C."}],"nameIdentifiers":[{"nameIdentifier":"651120","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Turco, F."}],"nameIdentifiers":[{"nameIdentifier":"651121","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉田 麻衣子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"651122","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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Magnetic shear effects on plasma transport and turbulence at high electron to ion temperature ratio in DIII-D and JT-60U plasmas","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Magnetic shear effects on plasma transport and turbulence at high electron to ion temperature ratio in DIII-D and JT-60U plasmas"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-03-09"},"publish_date":"2017-03-09","publish_status":"0","recid":"66144","relation_version_is_last":true,"title":["Magnetic shear effects on plasma transport and turbulence at high electron to ion temperature ratio in DIII-D and JT-60U plasmas"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:52:16.283068+00:00"}
