The mechanism of the Geodesic Acoustic Mode (GAM) is first introduced for a simple tokamak having a circular cross section. The theoretical basis of which was described a rather long time ago. The theory is then extended to include helical systems based on the perspective that the geodesic curvature of the confining magnetic\nfield plays an essential role. It is found that a short connection length in helical systems lends GAM oscillations different features from those in tokamaks. Special attention is paid to the low frequency range and a new branch is analyzed, which is referred to in this article as low frequency GAM. The zonal flow in the lowest frequency range is known as stationary zonal flow and known to have weak damping. Finally, an attempt is made to unify the theories of these two different frequency ranges.","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_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"Publisher version"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.jspf.or.jp/Journal/PDF_JSPF/jspf2005_12/jspf2005_12-jp.pdf","subitem_relation_type_select":"URI"}}]},"item_2_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"WATARI,  Tetsuo","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":"2022-03-14"}],"displaytype":"detail","filename":"jspf2005_12-998.pdf","filesize":[{"value":"408.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"jspf2005_12-998","url":"https://nifs-repository.repo.nii.ac.jp/record/671/files/jspf2005_12-998.pdf"},"version_id":"45e2e459-ad80-4fd6-a78d-bfedc6a07d5d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"geodesic acoustic mode","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"zonal flow","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"non-uniform potential field","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"neoclassical polarization current","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"ゾーナルフロー研究の現状と展望 ４．運動論によるゾーナルフローの解析, ４．２ ゾーナルフローとGAM 振動","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ゾーナルフロー研究の現状と展望 ４．運動論によるゾーナルフローの解析, ４．２ ゾーナルフローとGAM 振動"}]},"item_type_id":"2","owner":"3","path":["7"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-01-07"},"publish_date":"2014-01-07","publish_status":"0","recid":"671","relation_version_is_last":true,"title":["ゾーナルフロー研究の現状と展望 ４．運動論によるゾーナルフローの解析, ４．２ ゾーナルフローとGAM 振動"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T16:28:02.876442+00:00"}
