The result implies that the modelling of the transport should be reconsidered for low collisionality cases. A computer simulation study of transport in the ergodic region is required for understanding fundamental properties of collisionless ergodized-plasmas, estimating the transport coefficients, and reconstructing the modelling of the transport. In this paper, we report the simulation study of thermal transport in the ergodic region under the assumption of neglecting effects of an electric field, impurities and neutrals. Because of the simulations neglecting interactions with different particle-species and saving the computational time, we treat ions (protons) in our numerical-study of the transport. We find that the thermal diffusivity in the ergodic region is extremely small compared to the one predicted by the theory of field-line diffusion and that the diffusivity depends on both the collision frequency and the strength of RMPs even for the collisionless ergodized\"","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-957"}]},"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":"\"Kanno, R.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nunami, M.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Satake, S.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takamaru, H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okamoto, M.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ohyabu, N.\"","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"thermal transport","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"diffusion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ergodic region","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"chaotic field line","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"resonant magnetic perturbation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"collisionless toroidal plasma","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"delta f simulation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Monte-Carlo method","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":"Modelling of Ion Thermal Transport in Ergodic Region of Collisionless Toroidal Plasma","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Modelling of Ion Thermal Transport in Ergodic Region of Collisionless Toroidal Plasma","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":"9844","relation_version_is_last":true,"title":["Modelling of Ion Thermal Transport in Ergodic Region of Collisionless Toroidal Plasma"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T20:56:17.813837+00:00"}
