Capacitively Coupled Combline Antennas (CCCAs) were used for wave injection. The antennas are located on the outboard side and the top side of the vacuum vessel, and by reversing the toroidal magnetic field, it is possible to simulate the case of wave injection from the bottom\nside. The highest plasma current of 26.7 kA was achieved by top injection with the reversed toroidal magnetic field. According to numerical calculation using ray tracing and Fokker-Planck codes (GENRAY/CQL3D), the downshift of the parallel wavenumber helped the tail of the electron velocity distribution extend to higher energy than the other cases. Additionally, in order to evaluate the directionality of the wavenumber spectrum which is also important for efficient current drive, a finite element solver (COMSOL) was used. In order to avoid deterioration of the wavenumber spectrum, one limiter of the outboard antenna should be moved away toroidally by 70 mm from the current position, and the preferred distance between the antenna and the cutoff density layer is about 2 cm.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1585/pfr.13.3402114","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1880-6821","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":"YAJIMA, Satoru"}],"nameIdentifiers":[{"nameIdentifier":"501280","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"TAKASE, Yuichi"}],"nameIdentifiers":[{"nameIdentifier":"501281","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"EJIRI, Akira"}],"nameIdentifiers":[{"nameIdentifier":"501282","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"TSUJII, Naoto"}],"nameIdentifiers":[{"nameIdentifier":"501283","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"YAMAZAKI, Hibiki"}],"nameIdentifiers":[{"nameIdentifier":"501284","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Charles, P.
