In the stabilization experiments of m/n = 2/1 NTMs by electron cyclotron current drive of JT-60U, it has been clarified that the sawtooth collapses occur during or after the stabilization of m/n = 2/1 NTMs. It is also confirmed that the minimum safety factor, qmin, is nearly unity before and after the stabilization of an m/n = 2/1 NTM. While the flux pumping by ELM-NTM coupling was reported in DIII-D, the suppression of the sawtooth collapse is observed without ELMs in this study. On the other hand, it is observed that the sawtooth precursor appears during the stabilization of the m/n = 2/1 NTM accompanying the disappearance of the fluctuation of the n = 1 helical core (HC), which is induced by the m/n = 2/1 NTM. In addition, the modulation of the toroidal rotation velocity having the frequency of the n = 1 HC is observed in the core region. Because the helical flow with HCs is a possible source of the dynamo loop voltage in tokamaks, these observations suggest that the suppression of the sawtooth collapse in JT-60U is realized by the dynamo loop voltage due to the n = 1 HC induced by the m/n = 2/1 NTM. Our result indicates that n = 1 HCs induced by other MHD modes also may induce anomalous current transport in tokamaks.","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/ac04bb","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/10.1088/1361-6587/ac04bb","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0741-3335","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":"Bando, Takahiro"}],"nameIdentifiers":[{"nameIdentifier":"1014084","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takuma, Wakatsuki"}],"nameIdentifiers":[{"nameIdentifier":"1014085","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Honda, Mitsuru"}],"nameIdentifiers":[{"nameIdentifier":"1014086","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Akihiko, Isayama"}],"nameIdentifiers":[{"nameIdentifier":"1014087","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koji, Shinohara"}],"nameIdentifiers":[{"nameIdentifier":"1014088","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shizuo, Inoue"}],"nameIdentifiers":[{"nameIdentifier":"1014089","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Maiko, Yoshida"}],"nameIdentifiers":[{"nameIdentifier":"1014090","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Go, Matsunaga"}],"nameIdentifiers":[{"nameIdentifier":"1014091","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Manabu, Takechi"}],"nameIdentifiers":[{"nameIdentifier":"1014092","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Naoyuki, Oyama"}],"nameIdentifiers":[{"nameIdentifier":"1014093","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shunsuke, Ide"}],"nameIdentifiers":[{"nameIdentifier":"1014094","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takuma, Wakatsuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1014095","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Akihiko, Isayama","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1014096","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koji, Shinohara","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1014097","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shizuo, Inoue","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1014098","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Maiko, Yoshida","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1014099","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Go, Matsunaga","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1014100","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Manabu, Takechi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1014101","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Naoyuki, Oyama","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1014102","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shunsuke, Ide","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1014103","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":"Effect of m/n = 2/1 neoclassical tearing mode on sawtooth collapse in JT-60U","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effect of m/n = 2/1 neoclassical tearing mode on sawtooth collapse in JT-60U"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-07-20"},"publish_date":"2021-07-20","publish_status":"0","recid":"83942","relation_version_is_last":true,"title":["Effect of m/n = 2/1 neoclassical tearing mode on sawtooth collapse in JT-60U"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T18:49:54.182108+00:00"}
