The simulations include fast ions as passive test particles and were initialized with plasma profiles obtained from an integrated transport simulation. The beam-driven current produces a nonmonotonic safety factor profile with three q=2 rational surfaces. The resulting double or multiple kink-tearing instabilities redistribute both the bulk and fast particles in the inner half of the plasma. While the radial profiles appear to be flattened, the actual field topology and particle distributions are found to saturate in helical states. Moreover, because magnetic drifts are still large during the current ramp-up phase, there is a large difference between the topology of the magnetic field and 500 keV deuteron orbits. Fast ion phase space islands may thus appear and overlap at different times and in different regions than their magnetic counterparts.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1088/1361-6587/aad97b","subitem_relation_type_select":"DOI"}}]},"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":"ビアワーゲ, アンドレアス"}],"nameIdentifiers":[{"nameIdentifier":"497585","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"相羽, 信行"}],"nameIdentifiers":[{"nameIdentifier":"497586","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"松山, 顕之"}],"nameIdentifiers":[{"nameIdentifier":"497587","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"篠原, 孝司"}],"nameIdentifiers":[{"nameIdentifier":"497588","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"矢木, 雅敏"}],"nameIdentifiers":[{"nameIdentifier":"497589","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"ビアワーゲ アンドレアス","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"497590","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"相羽 信行","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"497591","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"松山 顕之","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"497592","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"篠原 孝司","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"497593","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"矢木 雅敏","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"497594","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":"Reconnecting instabilities in JT-60SA during current ramp-up with off-axis N-NB injection","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Reconnecting instabilities in JT-60SA during current ramp-up with off-axis N-NB injection"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-12-06"},"publish_date":"2018-12-06","publish_status":"0","recid":"49303","relation_version_is_last":true,"title":["Reconnecting instabilities in JT-60SA during current ramp-up with off-axis N-NB injection"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:20:12.466169+00:00"}
