Understanding the underlying laser-plasma interaction physics and resulting scaling to ultra-high intensities is of great importance for optimising such sources.  We therefore present experimental data of proton acceleration in a sheath field using the ultra-high intensity J-KAREN-P laser (10 J, 40 fs, 5x1021 W/cm2), allowing investigation at the high-intensity frontier.  \n\nWe will demonstrate a slower than expected increase in proton energy with decreasing focal spot size, and show that this is due to a reduced sheath lifetime for tight focal spots.  The proton beam spatial profile is found to vary with focal spot size, showing a narrow divergence beam at low energies (<10 MeV).  This, combined with our demonstration of a potentially high repetition rate experimental geometry provides an exciting platform for potential applications at the mid-to-low energy ranges.  \n","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":"JPS 74th Butsuri Gakkai 2019","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":"ドーバー, ニコラス ピーター"}],"nameIdentifiers":[{"nameIdentifier":"738876","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishiuchi, Mamiko"}],"nameIdentifiers":[{"nameIdentifier":"738877","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kevin Koga, James"}],"nameIdentifiers":[{"nameIdentifier":"738878","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakaki, Hironao"}],"nameIdentifiers":[{"nameIdentifier":"738879","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kondo, Kotaro"}],"nameIdentifiers":[{"nameIdentifier":"738880","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kiriyama, Hiromitsu"}],"nameIdentifiers":[{"nameIdentifier":"738881","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ogura, Koichi"}],"nameIdentifiers":[{"nameIdentifier":"738882","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Pirozhkov, Alexander"}],"nameIdentifiers":[{"nameIdentifier":"738883","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sagisaka, Akito"}],"nameIdentifiers":[{"nameIdentifier":"738884","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kando, Masaki"}],"nameIdentifiers":[{"nameIdentifier":"738885","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kondo, Kiminori"}],"nameIdentifiers":[{"nameIdentifier":"738886","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Dover, NicholasPeter","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"738887","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishiuchi, Mamiko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"738888","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kevin Koga, James","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"738889","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakaki, Hironao","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"738890","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kondo, Kotaro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"738891","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kiriyama, Hiromitsu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"738892","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ogura, Koichi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"738893","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Pirozhkov, Alexander","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"738894","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sagisaka, Akito","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"738895","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kando, Masaki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"738896","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kondo, Kiminori","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"738897","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":"Experimental investigation of sheath-driven proton beam parameters in the ultra-short pulse, ultra-high intensity regime","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Experimental investigation of sheath-driven proton beam parameters in the ultra-short pulse, ultra-high intensity regime"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-19"},"publish_date":"2019-03-19","publish_status":"0","recid":"74813","relation_version_is_last":true,"title":["Experimental investigation of sheath-driven proton beam parameters in the ultra-short pulse, ultra-high intensity regime"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T07:39:58.611682+00:00"}
