In order to assess the difficulties facing such scenarios, steady-state regimes have been explored on the tokamak à configuration variable (TCV) using the newly available 1 MW neutral beam injection (NBI) system. The operating space is extended towards plasmas that are closer to those expected in JT-60SA and ITER, i.e. with significant NBI and electron cyclotron resonance heating and current drive (ECRH/CD), bootstrap current and fast ion (FI) fraction. βN values up to 1.4 and 1.7 are obtained in lower single null L-mode (H98(y, 2) ∼ 0.8) and H-mode (H98(y, 2) ∼ 1) plasmas, respectively, at zero time averaged loop voltage and q95 ∼ 6. Fully non-inductive operation is not achieved with NBI alone, whose injection can even increase the loop voltage in the presence of EC waves. A strong contribution to the total plasma pressure of thermal and FIs from NBI is experimentally evidenced and confirmed by interpretative ASTRA and NUBEAM modeling, which further predicts that FI charge-exchange reactions are the main loss channel for NBH/CD efficiency. Internal transport barriers, which are expected to maximize the bootstrap current fraction, are not formed in either the electron or the ion channel in the plasmas explored to date, despite a significant increase in the toroidal rotation and FI fraction with NBI, which are known to reduce turbulence. First results on scenario development of high-βN fully non-inductive H-mode plasmas are also presented.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IOP Science"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1088/1741-4326/ab2bb6","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/ab2bb6","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":"Piron, C."}],"nameIdentifiers":[{"nameIdentifier":"997703","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Garcia, J."}],"nameIdentifiers":[{"nameIdentifier":"997704","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Agostini, M."}],"nameIdentifiers":[{"nameIdentifier":"997705","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fontana, M."}],"nameIdentifiers":[{"nameIdentifier":"997706","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Giruzzi, G."}],"nameIdentifiers":[{"nameIdentifier":"997707","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Gobbin, M."}],"nameIdentifiers":[{"nameIdentifier":"997708","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Goodman, T.P."}],"nameIdentifiers":[{"nameIdentifier":"997709","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Karpushov, A.N."}],"nameIdentifiers":[{"nameIdentifier":"997710","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kong, M."}],"nameIdentifiers":[{"nameIdentifier":"997711","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Merle, A."}],"nameIdentifiers":[{"nameIdentifier":"997712","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"J.
