Once the W impurities sputtered from the PFCs penetrate into the core plasma, the large radiation cooling and fuel dilution, which leads to the deterioration of the core plasma performance, take place. To understand and to control W impurity transport are indispensable for future fusion reactors. In order to understand W transport, we are continuing to develop the kinetic impurity transport code IMPGYRO for SOL/divertor in fusion reactors. The IMPGYRO has obtained following unique features compared to other existing kinetic impurity transport codes through the 15-years development activity; (i) the exact Larmor motion of impurity ions are computed so that the effects of drifts are automatically taken into account, (ii) the Coulomb collision between impurities and background plasma ions are modelled by the Binary Collision Method which kinetically calculates more precise friction and thermal forces, and (iii) the background plasma transport and impurity transport are computed self-consistently by the coupled calculation with SOL/divertor plasma transport code such as SOLPS-ITER. Although the IMPGYRO transport model has significantly improved from the initial development phase, the modelling improvement of the IMPGYRO has never been described in detail. In this paper, (a) the current W generation/transport model, and (b) the coupling strategy between the SOLPS-ITER and the IMPGYRO are summarized. The new results (c) the check of the prompt re-deposition model of the IMPGYRO, and (d) the further extension of the Coulomb collision modelling of the IMPGYRO towards the neoclassical (NC) transport handling capability has been performed. The effects of the NC transport processes on a simple circular tokamak geometry are compared with the anomalous diffusion by means of the extended IMPGYRO to obtain better understanding of cross-field transport process of W. The results show that the NC transport process may become non-negligible compared to the anomalous diffusion at least in this configuration. Based on these recent improvements, the present version of the IMPGYRO is very useful tool for understanding and prediction of W transport in SOL/divertor regions of fusion devices.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier B.V."}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.cpc.2019.106979","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://doi.org/10.1016/j.cpc.2019.106979","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0010-4655","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":"Yamoto, Shohei"}],"nameIdentifiers":[{"nameIdentifier":"998366","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Homma, Yuuki"}],"nameIdentifiers":[{"nameIdentifier":"998367","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hoshino, Kazuo"}],"nameIdentifiers":[{"nameIdentifier":"998368","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Toma, Mitsunori"}],"nameIdentifiers":[{"nameIdentifier":"998369","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hatayama, Akiyoshi"}],"nameIdentifiers":[{"nameIdentifier":"998370","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shohei, Yamoto","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"998371","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yuuki, Homma","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"998372","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":"IMPGYRO: The full-orbit impurity transport code for SOL/divertor and its successful application to tungsten impurities","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"IMPGYRO: The full-orbit impurity transport code for SOL/divertor and its successful application to tungsten impurities"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-01-07"},"publish_date":"2020-01-07","publish_status":"0","recid":"78343","relation_version_is_last":true,"title":["IMPGYRO: The full-orbit impurity transport code for SOL/divertor and its successful application to tungsten impurities"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:49:17.713577+00:00"}
