It is found that the size of a dangerous island should increase with beta but that a destruction of the equilibrium at low beta is avoided because the rotational transform evolves to exclude the rational surface concerned.  At higher beta there is evidence of near-resonant flux surface deformations which may lead to an equilibrium limit.  A reconnected equilibrium at still higher beta exhibits a double island structure which is similar to homoclinic phase portraits which have been observed after separatrix reconnection in Hamiltonian systems. Physical mechanism of the island formation in finite-beta helical equilibria is investigated to confirm there are cases where the global effect of the Pfirsch-Schluter currents is important.  The earlier theory is extended to elucidate the occurrence of the complete self-healing of island when the resistive interchange criterion satisfied.","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-305"}]},"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":"Nakajima,  N.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ichiguchi,  K.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Merkel,  P.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nuhrenberg,  J.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Schwenn,  U.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Gardner,  H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Bhattacharjee,  A.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hegna,  C.C.\"","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"helical system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"heliac","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"heliotron","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"torsatron","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"stellarator","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"three dimensional equilibrium","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"beta limit","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"}]},"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":"Behavior of Magnetic Islands in 3D MHD Equilibria of Helical Devices","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Behavior of Magnetic Islands in 3D MHD Equilibria of Helical Devices","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":"9611","relation_version_is_last":true,"title":["Behavior of Magnetic Islands in 3D MHD Equilibria of Helical Devices"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T20:57:29.947679+00:00"}
