The coordinate transformation from the Hamada to the Boozer coordinate system is performed using a transformation function, which is easily calculated with the knowledge of the magnetic field strength only. In non-axisymmetric systems, the Fourier spectrum of the magnetic field strength |vec{B}| in the Hamada coordinate system is broader than that in the Boozer coordinate system and the leading modes of |vec{B}| in the Hamada coordinate system significantly deviate from a simple model field in comparison with the Boozer coordinate system. The Boozer coordinate system is suitable for numerical calculations, especially, for neoclassical and orbit calculations in non-axisymmetric 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-173"}]},"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":"\"Nakajima,  N.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Todoroki,  J.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okamoto,  M.\"","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Magnetic coordinate system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Hamada coordinate system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Boozer coordinate system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Straight magnetic field line coordinate system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"coordinate transformation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"non-axisymmetric system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Fourier spectrum","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":"On Relation between Hamada and Boozer Magnetic Coordinate System","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"On Relation between Hamada and Boozer Magnetic Coordinate System","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":"10033","relation_version_is_last":true,"title":["On Relation between Hamada and Boozer Magnetic Coordinate System"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T20:54:18.047453+00:00"}
