Abstract

An intense activity on high brightness photo-injectors for SASE-FEL experiments and facilities, is being carried out, since 2003, in the Research Site of the INFN Frascati Laboratory, Rome, in collaboration with CNR and ENEA. SPARC is the 150 MeV photo-injector, in advanced phase of commissioning at LNF. The electron beam, which drives a 530 nm FEL experiment, is being characterized in terms of emittance, energy spread, peak current. The matching with the linac confirmed the theoretical prediction of emittance compensation based on the “invariant envelope” matching. The demonstration of the “velocity bunching” technique is in progress too. The SPARC photo-injector is the test facility for the soft-X FEL project named SPARX [1], that is based on the generation of ultra high peak brightness electron beams at the energies of 1.2 and 2.4 GeV generating radiation in the 1.5-13 nm range. SPARX will be realized in the Tor- Vergata University campus. In this paper we report the experimental results obtained so far with SPARC and the design status of the SPARX project.
