The quantum electrodynamics processes in the course of the interaction of an ultra-intense laser with a solid target are studied via three-dimensional particle-in-cell simulations, revealing the generation of copious γ-photons and electron–positron pairs. A parametric study of the laser polarisation, target thickness and electron number density shows that a radially polarised laser provides the optimal regime for γ-photon generation. By varying the laser power in the range of 1 to 300 PW we find the scaling of the laser to γ-photon energy conversion efficiency. The laser-generated γ-photon interaction with a high-Z target is further studied using Monte Carlo simulations revealing further electron–positron pair generation and radioactive nuclide creation.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1017/S0022377821001318","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://www.cambridge.org/core/journals/journal-of-plasma-physics/article/abs/gammaray-flash-in-the-interaction-of-a-tightly-focused-singlecycle-ultraintense-laser-pulse-with-a-solid-target/71CCB21A45DF567FBAA2CE0CAFA46973","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0022-3778","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":"Hadjisolomou, P."}],"nameIdentifiers":[{"nameIdentifier":"1036447","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Jeong, T.M."}],"nameIdentifiers":[{"nameIdentifier":"1036448","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Valenta, P."}],"nameIdentifiers":[{"nameIdentifier":"1036449","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kolenaty, D."}],"nameIdentifiers":[{"nameIdentifier":"1036450","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Versaci, R."}],"nameIdentifiers":[{"nameIdentifier":"1036451","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"V., Olšovcová"}],"nameIdentifiers":[{"nameIdentifier":"1036452","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ridgers, C.P."}],"nameIdentifiers":[{"nameIdentifier":"1036453","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Bulanov, Sergey"}],"nameIdentifiers":[{"nameIdentifier":"1036454","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Bulanov, Sergey","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1036455","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":"Gamma-ray flash in the interaction of a tightly focused single-cycle ultra-intense laser pulse with a solid target","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Gamma-ray flash in the interaction of a tightly focused single-cycle ultra-intense laser pulse with a solid target"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-03-15"},"publish_date":"2022-03-15","publish_status":"0","recid":"85323","relation_version_is_last":true,"title":["Gamma-ray flash in the interaction of a tightly focused single-cycle ultra-intense laser pulse with a solid target"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T17:31:44.201246+00:00"}
