About 200 ms after the start of NBI heating, a slow L-H transition takes place, which evolves into a fully-developed H-mode spending a few 100ms. During this slow transition process, a smooth decrease in Dα emission, increase in the edge line-averaged electron density and steepening of ion temperature take place. The Er-well bottom value at ~3 cm inside the LCFS becomes large up to -40 kV/m as a similar time-scale of the change in the density [5], while the jr shows a local Max. value of 0.01-0.02 A/m2 just after a slow L-H transition and its broader radial structure propagates toward plasma core region in the time-scale of ~100ms as seen in the pedestal development. On the other hand, we found that a localized jr structure with positive or negative polarities of its absolute peak value of 0.4-0.5 A/m2 occurred spontaneously during the later ELM-free H-phase at which a complex multi-stage Er-transition was seen with a fast time-scale. This observation suggests a co-existence of the non-linear physical mechanism for the jr generation at the plasma edge region in terms of its variation in the time-scale and radial structure. Comparison with a theoretical model, including fast-ion loss current due to the ripple loss effect, is also discussed.","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":"46th EPS 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":"Kamiya, Kensaku"}],"nameIdentifiers":[{"nameIdentifier":"769082","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Itoh, Kimitaka"}],"nameIdentifiers":[{"nameIdentifier":"769083","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sanae-I, Itoh"}],"nameIdentifiers":[{"nameIdentifier":"769084","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Honda, Mitsuru"}],"nameIdentifiers":[{"nameIdentifier":"769085","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kamiya, Kensaku","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"769086","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Honda, Mitsuru","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"769087","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":"Structure generation of the edge radial current during the L-H transition on JT-60U","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Structure generation of the edge radial current during the L-H transition on JT-60U"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-07-16"},"publish_date":"2019-07-16","publish_status":"0","recid":"76281","relation_version_is_last":true,"title":["Structure generation of the edge radial current during the L-H transition on JT-60U"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:31:03.617699+00:00"}
