The External-Injection experiment at the SPARC_LAB facility

Abstract

At the SPARC_LAB facility of INFN-LNF we are installing a transport lines for ultra-short electron bunches and another for ultra-intense laser pulses,generated by the SPARC photo-injector and by the FLAME laser in asynchronized fashion at the tens of fs level,to co-propagate inside a hydrogen filled glass capillary,in order to perform acceleration of the electron bunch by a plasma wave driven by the laser pulse.The main aim of this experiment is to demonstrate that a high brightness electron beam can be accelerated by a plasma wave without any significant degradation of its quality.Motivations of the technical choices are made and expected performances are reporte
