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 Da 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, 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_10003_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ocs.ciemat.es/EPS2019PAP/pdf/P5.1015.pdf","subitem_relation_type_select":"URI"}}]},"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":"769349","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Itoh, Kimitaka"}],"nameIdentifiers":[{"nameIdentifier":"769350","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sanae-I, Itoh"}],"nameIdentifiers":[{"nameIdentifier":"769351","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Honda, Mitsuru"}],"nameIdentifiers":[{"nameIdentifier":"769352","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kamiya, Kensaku","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"769353","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Honda, Mitsuru","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"769354","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 paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"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":"10003","owner":"1","path":["2"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-07-17"},"publish_date":"2019-07-17","publish_status":"0","recid":"76290","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":"2023-05-16T00:30:43.375982+00:00"}
