LFMs show the low mode frequencies (<20 Hz) with the rotation direction to the counter-current direction (ctr-direction) toroidally, even if strong injection power to the co-current direction (co-direction) is applied by tangential neutral beam injections. As a candidate to drive the rotation to the ctr-direction, the neoclassical toroidal viscosity (NTV) torque is investigated in this study. Indeed, when a LFM is observed, the estimated 'offset velocity' of the NTV torque is larger than the observed toroidal velocity around the q = 2 surface and results in the torque to the ctr-direction (ctr-torque). The torque balance between the NTV torque and the torque induced by the eddy current on the resistive wall is investigated. It is found that the rotation to the ctr-direction having the low mode frequency is obtained as the result of the ctr-torque to the offset velocity. Our investigation suggests the requirement to include the NTV torque in the modeling on the mode locking of neoclassical tearing modes 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/ac11b7","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/ac11b7/meta","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":"Takahiro, Bando"}],"nameIdentifiers":[{"nameIdentifier":"1023343","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mitsuru, Honda"}],"nameIdentifiers":[{"nameIdentifier":"1023344","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shizuo, Inoue"}],"nameIdentifiers":[{"nameIdentifier":"1023345","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Maiko, Yoshida"}],"nameIdentifiers":[{"nameIdentifier":"1023346","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Go, Matsunaga"}],"nameIdentifiers":[{"nameIdentifier":"1023347","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Akihiko, Isayama"}],"nameIdentifiers":[{"nameIdentifier":"1023348","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Manabu, Takechi"}],"nameIdentifiers":[{"nameIdentifier":"1023349","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koji, Shinohara"}],"nameIdentifiers":[{"nameIdentifier":"1023350","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shuhei, Sumida"}],"nameIdentifiers":[{"nameIdentifier":"1023351","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takahiro, Bando","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1023352","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mitsuru, Honda","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1023353","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shizuo, Inoue","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1023354","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Maiko, Yoshida","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1023355","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Go, Matsunaga","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1023356","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Akihiko, Isayama","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1023357","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Manabu, Takechi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1023358","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koji, Shinohara","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1023359","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shuhei, Sumida","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1023360","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":"Torque to counter-current direction driving low frequency tearing modes in JT-60U","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Torque to counter-current direction driving low frequency tearing modes in JT-60U"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-11-13"},"publish_date":"2021-11-13","publish_status":"0","recid":"84811","relation_version_is_last":true,"title":["Torque to counter-current direction driving low frequency tearing modes in JT-60U"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T18:10:50.505660+00:00"}
