The structure of the magnetic island with m/n = 1/1 (where, m and n are poloidal and toroidal mode number, respectively) can be estimated from the perturbed magnetic field appearing when a magnetic island changes. To measure the toroidal profile of the perturbed magnetic field δb1  originating from the plasma, a toroidal array of magnetic flux loops is set up in the LHD. The toroidal profile of δb1 is then spatially Fourier decomposed to determine the amplitude of the n = 1 component, δb1n=1  and its phase, φn=1 which correspond the change of the island width and the toroidal position of the X-point of the island, respectively. Therefore, the information about the magnetic island structure can be obtained from δb1n=1 and φn=1. In case the island width becomes larger than the seed island, measurements show that δb1n=1 is non-zero and φn=1  is temporally constant. A non-zero δb1n=1 can also be observed when the island width becomes smaller than the seed island. In this case, the angle φn=1 shifts by about π[rad] compared with the increasing case and the δb1n=1 is limited to a certain value which corresponding to the magnetic field suppressing the seed island.","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"プラズマ・核融合学会"}]},"item_2_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1585/pfr.2.S1094","subitem_relation_type_select":"DOI"}}]},"item_2_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"? 2007 The Japan Society of Plasma Science and Nuclear Fusion Research"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"NARUSHIMA,  Y.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"WATANABE,  K.Y.","creatorNameLang":"en"}],"familyNames":[{}],"givenNames":[{}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SAKAKIBARA,  S.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OHYABU,  N.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YAMADA,  H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NARIHARA,  K.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YAMADA,  I.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MORISAKI,  T.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"INAGAKI,  S.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NAGAYAMA,  Y.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KOMORI,  A.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"LHD, exp. group","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"COOPER,  W.A.","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":"2016-03-23"}],"displaytype":"detail","filename":"pfr2007_02-S1094.pdf","filesize":[{"value":"574.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"pfr2007_02-S1094.pdf","url":"https://nifs-repository.repo.nii.ac.jp/record/392/files/pfr2007_02-S1094.pdf"},"version_id":"88ffe003-b99c-4bee-b3eb-010ce4923a11"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Large Helical Device","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"magnetic island","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"magnetic diagnostics","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"self-healing","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Magnetic Diagnostics of Magnetic Island in LHD","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Magnetic Diagnostics of Magnetic Island in LHD","subitem_title_language":"en"}]},"item_type_id":"2","owner":"3","path":["7"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-05-02"},"publish_date":"2011-05-02","publish_status":"0","recid":"392","relation_version_is_last":true,"title":["Magnetic Diagnostics of Magnetic Island in LHD"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2024-04-08T02:16:10.228997+00:00"}
