This presentation reports recent advances that were made in simulating these wave-particle interactions numerically using a hybrid model, which includes realistic beam ion sources and beam-bulk collisions, so that it is valid over a wide range of time scales: from Alfvenic oscillations (μs scale) to collisional slow-down (>100 ms). In order to be able to simulate the long-time evolution on available supercomputers, the so-called multi-phase method is employed. Although it was originally intended to improve the accuracy of numerical predictions in cases where the system settles in a relatively steady state and study aspects such as profiles resiliency, it turns out that this method even allows us to reproduce multiple cycles of so-called abrupt large-amplitude events (ALE), as seen in JT-60U. The latest insights on ALE physics obtained with such simulations are discussed.","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":"2018 Korean Physical Society (KPS) Fall Meeting, Pioneer Symposium 8: 　　　　“Data-based Plasma Science and Simulation for the Computer Aided Design”","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":"ビアワーゲ, アンドレアス"}],"nameIdentifiers":[{"nameIdentifier":"722745","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"ビアワーゲ アンドレアス","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"722746","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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Energetic-ion-driven instabilities and transport: Multi-time-scale simulations, validation, predictions and insights","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Energetic-ion-driven instabilities and transport: Multi-time-scale simulations, validation, predictions and insights"}]},"item_type_id":"10005","owner":"1","path":["27"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-01-28"},"publish_date":"2019-01-28","publish_status":"0","recid":"73355","relation_version_is_last":true,"title":["Energetic-ion-driven instabilities and transport: Multi-time-scale simulations, validation, predictions and insights"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:30:12.592164+00:00"}
