The EC system incorporates two subsystems: X2 (second harmonic) used for electron heating up to cutoff density with efficient current drive; X3 extends the density range for EC heating up to higher density\n (cutoff limit) suitable for H-mode confinement regime. The X2+X3 EC power available for the experiments studied here was 2.5 MW. The maximal NB power was up to 1.05 MW, using the tangentially injected beam with full energy of 25 keV at maximal power. Compared to the past, when fully non-inductive plasmas sustained using EC waves only were obtained, the operating space of advanced tokamak scenarios in TCV has been now extended towards higher plasma current and density with NB+EC heating scheme. These scenarios, characterized by high βN, high non-inductive current fraction and a relevant energetic particle (EP) population fraction (~10% ne) are envisaged as potential candidates for the regular future tokamak reactor operation due to their high fusion power generation and low inductive current requirements and outline the basis for future JT60-SA high-β experimental program. An internal transport barrier can be generated by reversing the q-profile using EC current-drive (ECCD). A strong contribution of bulk ions and EP to plasma pressure and total energy in performed plasma discharges is illustrated in Figure 1: the plasma β is clearly decorrelated from electron thermal energy and this is caused by an interplay between neutral beam injection (NBI) and ECH.","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":"The 45th European Physical Society Conference on Plasma Physics","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":"Vallar, M."}],"nameIdentifiers":[{"nameIdentifier":"717624","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Agostini, M."}],"nameIdentifiers":[{"nameIdentifier":"717625","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Bolzonella, T."}],"nameIdentifiers":[{"nameIdentifier":"717626","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Coda, S."}],"nameIdentifiers":[{"nameIdentifier":"717627","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Garcia, J."}],"nameIdentifiers":[{"nameIdentifier":"717628","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Geiger, B."}],"nameIdentifiers":[{"nameIdentifier":"717629","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Goodman, T."}],"nameIdentifiers":[{"nameIdentifier":"717630","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Gorelenkova, M."}],"nameIdentifiers":[{"nameIdentifier":"717631","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Karpushov, A.N."}],"nameIdentifiers":[{"nameIdentifier":"717632","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kurki-Suonio, T."}],"nameIdentifiers":[{"nameIdentifier":"717633","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Piron, C."}],"nameIdentifiers":[{"nameIdentifier":"717634","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Pigatto, L."}],"nameIdentifiers":[{"nameIdentifier":"717635","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sauter, O."}],"nameIdentifiers":[{"nameIdentifier":"717636","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Vianello, N."}],"nameIdentifiers":[{"nameIdentifier":"717637","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Vincenzi, P."}],"nameIdentifiers":[{"nameIdentifier":"717638","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉田, 麻衣子"}],"nameIdentifiers":[{"nameIdentifier":"717639","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉田 麻衣子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"717640","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":"Nonlinear contribution of neutral beam injection in TCV EC-heated advanced tokamak scenarios","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Nonlinear contribution of neutral beam injection in TCV EC-heated advanced tokamak scenarios"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-07-02"},"publish_date":"2018-07-02","publish_status":"0","recid":"72843","relation_version_is_last":true,"title":["Nonlinear contribution of neutral beam injection in TCV EC-heated advanced tokamak scenarios"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:35:26.338080+00:00"}
