Disruption avoidance by real-time locked mode prevention or unlocking with ECRH was thoroughly documented, using magnetic and radiation triggers. Runaway generation with high-Z noble-gas injection and runaway dissipation by subsequent Ne or Ar injection were studied for model validation. The new 1-MW NBI has expanded the parameter range, now encompassing ELMy H-modes in an ITER-like shape and stationary non-inductive discharges sustained by ECCD and NBCD. In H-mode, the pedestal pressure and plasma stored energy are insensitive to fueling, whereas nitrogen seeding moves the pedestal outwards and increases the stored energy. High fueling at high triangularity is key to accessing the attractive smallELM (type-II) regime. Turbulence is reduced in the core at negative triangularity, consistent with increased confinement and in accord with global gyrokinetic simulations. The GAM, possibly coupled with avalanche events, has been linked with particle flow to the wall in diverted plasmas. Detachment, SOL transport, and turbulence were studied in L- and H-mode in both standard and alternative configurations (snowflake, super-X, and beyond). The detachment process is caused by power “starvation” reducing the ionization source, with volume recombination playing only a minor role. Partial detachment in Hmode is obtained with impurity seeding and is insensitive to divertor geometry. In the attached L-mode phase, increasing the outer connection length reduces the in-out heat-flow asymmetry. A doublet plasma, featuring an internal X-point, was achieved successfully, and a transport barrier was observed in the mantle just outside the internal separatrix. In the near future variable configuration baffles and cryo-pumping will be introduced to investigate the effect of divertor closure on exhaust and performance, and 3.5-MW ECRH and 1-MW NBI heating will be added.","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":"The 27th IAEA Fusion Energy Conference ","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":"CODA, S."}],"nameIdentifiers":[{"nameIdentifier":"658296","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshida, M."}],"nameIdentifiers":[{"nameIdentifier":"658297","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"team, TCV"}],"nameIdentifiers":[{"nameIdentifier":"658298","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"MST1, team EUROfusion"}],"nameIdentifiers":[{"nameIdentifier":"658299","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉田 麻衣子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"658300","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":"PHYSICS RESEARCH ON THE TCV TOKAMAK FACILITY: FROM CONVENTIONAL TO ALTERNATIVE SCENARIOS AND BEYOND","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"PHYSICS RESEARCH ON THE TCV TOKAMAK FACILITY: FROM CONVENTIONAL TO ALTERNATIVE SCENARIOS AND BEYOND"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-11-13"},"publish_date":"2018-11-13","publish_status":"0","recid":"66972","relation_version_is_last":true,"title":["PHYSICS RESEARCH ON THE TCV TOKAMAK FACILITY: FROM CONVENTIONAL TO ALTERNATIVE SCENARIOS AND BEYOND"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:42:54.330737+00:00"}
