This work presents a target geometry where two symmetric side holes and a central hole are drilled into the foil. A study of the various side-hole and central-hole length combinations is performed with two-dimensional particle-in-cell simulations for polyethylene targets and a laser intensity of  . The holed targets show a remarkable increase of the conversion efficiency, which corresponds to a different target configuration for electrons, protons and carbon ions. Furthermore, diffraction of the laser pulse leads to a directional high energy electron beam, with a temperature of  , or seven times higher than in the case of a flat foil. The higher conversion efficiency consequently leads to a significant enhancement of the maximum proton energy from holed targets.","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/S0022377820000379","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/towards-laser-ion-acceleration-with-holed-targets/F009D11B07477AE83E857D50B1D60DB0","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, Prokopis"}],"nameIdentifiers":[{"nameIdentifier":"881522","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Bulanov"}],"nameIdentifiers":[{"nameIdentifier":"881523","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Korn, G."}],"nameIdentifiers":[{"nameIdentifier":"881524","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Bulanov, Sergey","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"881525","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":"Towards laser ion acceleration with holed targets","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Towards laser ion acceleration with holed targets"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-08-04"},"publish_date":"2020-08-04","publish_status":"0","recid":"80275","relation_version_is_last":true,"title":["Towards laser ion acceleration with holed targets"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:40:06.435853+00:00"}
