At higher pressures there is evidence of near-resonant flux surface deformations which may lead to an equilibrium limit.  A reconnected equilibrium at still higher pressures exhibits a double island structure which is similar t homoclinic phase portraits which have been observed after separatrix reconnection in Hamiltonian systems.","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-308"}]},"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":"\"Hayashi,  T.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sato,  T.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Gardner,  H.J.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Meiss,  J.D.\"","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"heliac","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"three dimensional equilibrium","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"magnetic island","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"self-healing of magnetic island","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"finite pressure effect","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"homoclinic bifurcation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"stellarator","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":"Evolution of Magnetic Islands in a Heliac","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Evolution of Magnetic Islands in a Heliac","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":"9608","relation_version_is_last":true,"title":["Evolution of Magnetic Islands in a Heliac"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T20:57:31.840454+00:00"}
