Unbalancing these currents leads to spatial axis configuration. It is reported here that the bootstrap current is strongly affected by the imbalance of these currents. When the ratio of the currents in the two helical coils is small enough, the bootstrap current flows in a direction so as to decrease the rotational transform because of the enhancement of the bumpiness component of the magnetic field as well as the spatial axis component. This leads to improved stability.","subitem_description_type":"Abstract"}]},"item_5_source_id_10":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0915-633X","subitem_source_identifier_type":"ISSN"}]},"item_5_text_8":{"attribute_name":"報告書番号","attribute_value_mlt":[{"subitem_text_value":"NIFS-492"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ichiguchi,  K.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakajima,  N.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okamoto,  M.","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-03-11"}],"displaytype":"detail","filename":"NIFS-492.pdf","filesize":[{"value":"657.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"NIFS-492.pdf","url":"https://nifs-repository.repo.nii.ac.jp/record/9640/files/NIFS-492.pdf"},"version_id":"2248c1bf-9aee-48d4-b13f-9f2a82cbd97f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"bootstrap current","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Large Helical Device(LHD)","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"spatial axis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Heliotron/Torsatron","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"MHD","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Mercier stability","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"unbalanced helical coil currents.","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"Bootstrap Current in the Large Helical Device with Unbalanced Helical Coil Currents","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Bootstrap Current in the Large Helical Device with Unbalanced Helical Coil Currents","subitem_title_language":"en"}]},"item_type_id":"5","owner":"3","path":["32"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-02-05"},"publish_date":"2010-02-05","publish_status":"0","recid":"9640","relation_version_is_last":true,"title":["Bootstrap Current in the Large Helical Device with Unbalanced Helical Coil Currents"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T20:44:04.197573+00:00"}
