New insights concerning the nonadiabatic chirp onset and the effects of beating due to interference between multiple chirps are reported. Preliminary results of applying ORBIT to chirping modes observed in JT-60U are also presented.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"  第37回 プラズマ・核融合学会 年会","subitem_description_type":"Other"}]},"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":"Bierwage, Andreas"}],"nameIdentifiers":[{"nameIdentifier":"914384","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Roscoe, B.
