We have assessed, by simulation, the impact and role of the kinetic effect of ion heat conductivity (abbreviated as ion KE in this paper) on DEMO-relevant tokamak SOL plasma, using the Japanese demonstration tokamak reactor concept JA DEMO. A series of test simulations, where the ion KE is modeled by a widely used free-streaming energy (FSE)-limited model, has demonstrated: (a) the ion KE decreases the ion parallel heat flux density in JA DEMO SOL (at the baseline operation scenario) around the X-point and further upstream of the low-field side (LFS) area along the separatrix, where the parallel collisionality is smaller. Up to 40%–60% decrease is observed, compared to the case without (w/o) ion KE, among the test cases where the ion KE level is scanned over the possible range (i.e. parameter αi of the FSE-limited model is varied over $0.2 \\leqslant \\alpha _{\\textrm{i}} \\leqslant 2.0$); (b) the ion KE leads to significant increase in the ion temperature Ti (up to 600% increase) and significant decrease in the ion density ni (up to −80%) over wide area of the SOL upstream. Energy balance analysis has suggested that the ion KE affects the upstream ni and Ti by the power of 0.4 and −0.4, respectively, of the flux limiting factor, as long as spatial changes in plasma parameters are moderate. The results of this study serve as a fundamental assessment of the ion KE for DEMO- relevant SOL plasma, clarifying the need for further sophistication of the model toward more quantitative prediction.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IOP Science "}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1088/1361-6587/ac48bd","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://iopscience.iop.org/article/10.1088/1361-6587/ac48bd","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0741-3335","subitem_source_identifier_type":"ISSN"}]},"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":"Yuuki, Homma"}],"nameIdentifiers":[{"nameIdentifier":"1041521","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yuuki, Homma","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1041522","nameIdentifierScheme":"WEKO"}]}]},"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":"Assessment of the impact of the kinetic effect of ion parallel heat conduction on DEMO relevant SOL plasma using integrated SOL divertor code SONIC","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Assessment of the impact of the kinetic effect of ion parallel heat conduction on DEMO relevant SOL plasma using integrated SOL divertor code SONIC"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-03-07"},"publish_date":"2022-03-07","publish_status":"0","recid":"85339","relation_version_is_last":true,"title":["Assessment of the impact of the kinetic effect of ion parallel heat conduction on DEMO relevant SOL plasma using integrated SOL divertor code SONIC"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T17:22:53.452179+00:00"}
