The simulation results show that the ballooning-like instabilities on an intermediate spatial scale induce disordering of structures in the barrier region and a drop in the central pressure. It was revealed that the core pressure fall is related to disordering of the magnetic field structure. The simulation results are compared qualitatively with the experimental observations of the collapse events in the superdense core state of the Large Helical Device (LHD). Compared with our previous simulation studies of similar situations in the spherical tokamak (ST) plasma, the results for the helical cases show milder collapses than those in the ST case.","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.3.S1034","subitem_relation_type_select":"DOI"}}]},"item_2_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"? 2008 The Japan Society of Plasma Science and Nuclear Fusion Resear"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"MIZUGUCHI,  Naoki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SUZUKI,  Yasuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OHYABU,  Nobuyoshi","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":"pfr2008_03-S1034.pdf","filesize":[{"value":"760.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"pfr2008_03-S1034.pdf","url":"https://nifs-repository.repo.nii.ac.jp/record/437/files/pfr2008_03-S1034.pdf"},"version_id":"4e7f1523-10b7-4e66-a028-9775ab590dbc"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"magnetohydrodynamics","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"collapse","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"helical system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"simulation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"superdense core","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":"Nonlinear Simulation of Collapse Phenomenon in Helical Plasma with a Large Pressure Gradient","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Nonlinear Simulation of Collapse Phenomenon in Helical Plasma with a Large Pressure Gradient","subitem_title_language":"en"}]},"item_type_id":"2","owner":"3","path":["7"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-04-04"},"publish_date":"2011-04-04","publish_status":"0","recid":"437","relation_version_is_last":true,"title":["Nonlinear Simulation of Collapse Phenomenon in Helical Plasma with a Large Pressure Gradient"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T16:42:43.261783+00:00"}
