Results of comprehensive analyses performed by a number of complementary techniques, e.g. a range of microscopy methods, electron and ion spectroscopy, liquid scintillography and thermal desorption, are summarized by following points: (a) Total amount of dust collected by vacuum cleaning after three campaigns is about 1–1.4 g per campaign (19.1–23.5 h plasma operation), i.e. over 100 times smaller than in JET operated with carbon walls (i.e. in JETC). (b) Two major categories of Be dust are identified: flakes of co-deposits formed on PFC and droplets (2–10 μm in diameter). Small quantifies, below 1 g, of Be droplets and splashes are associated mainly with melting of beryllium limiters. (c) Tungsten dust occurs mainly as partly molten flakes originating from the W-coated tiles.","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 13the International Symposium on Fusion Nuclear Technology(ISFNT-13)","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":"Rubel, M."}],"nameIdentifiers":[{"nameIdentifier":"716900","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Widdowson, A."}],"nameIdentifiers":[{"nameIdentifier":"716901","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Grzonka, J."}],"nameIdentifiers":[{"nameIdentifier":"716902","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Moon, Sunwoo"}],"nameIdentifiers":[{"nameIdentifier":"716903","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Petersson, P."}],"nameIdentifiers":[{"nameIdentifier":"716904","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fortuna-Zaleśna, E."}],"nameIdentifiers":[{"nameIdentifier":"716905","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Baron-Wiechec, A."}],"nameIdentifiers":[{"nameIdentifier":"716906","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ashikawa, N."}],"nameIdentifiers":[{"nameIdentifier":"716907","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Asakura, Nobuyuki"}],"nameIdentifiers":[{"nameIdentifier":"716908","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hatano, Y."}],"nameIdentifiers":[{"nameIdentifier":"716909","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Isobe, Kanetsugu"}],"nameIdentifiers":[{"nameIdentifier":"716910","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kurotaki, Hironori"}],"nameIdentifiers":[{"nameIdentifier":"716911","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Masuzaki, S."}],"nameIdentifiers":[{"nameIdentifier":"716912","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Oya, Y."}],"nameIdentifiers":[{"nameIdentifier":"716913","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Oyaizu, Makoto"}],"nameIdentifiers":[{"nameIdentifier":"716914","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tokitani, M."}],"nameIdentifiers":[{"nameIdentifier":"716915","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Contributors, JET"}],"nameIdentifiers":[{"nameIdentifier":"716916","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"朝倉 伸幸","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"716917","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"磯部 兼嗣","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"716918","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"黒滝 宏紀","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"716919","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小柳津 誠","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"716920","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":"Dust Generation in Tokamaks: Overview of Beryllium and Tungsten Dust Studies in JET with the ITER-Like Wall","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Dust Generation in Tokamaks: Overview of Beryllium and Tungsten Dust Studies in JET with the ITER-Like Wall"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-05-02"},"publish_date":"2018-05-02","publish_status":"0","recid":"72774","relation_version_is_last":true,"title":["Dust Generation in Tokamaks: Overview of Beryllium and Tungsten Dust Studies in JET with the ITER-Like Wall"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:36:12.949541+00:00"}
