The SPARX project consists in an X-ray-FEL facility
jointly supported by MIUR (Research Department of
Italian Government), Regione Lazio, CNR, ENEA, INFN
and Rome University Tor Vergata. It is the natural
extension of the ongoing activities of the SPARC
collaboration. The aim is the generation of electron beams
characterized by ultra-high peak brightness at the energy
of 1 and 2 GeV, for the first and the second phase
respectively. The beam is expected to drive a single pass
FEL experiment in the range of 13.5÷6 nm and 6÷1.5 nm,
at 1 GeV and 2 GeV respectively, both in SASE and
SEEDED FEL configurations. A hybrid scheme of RF
and magnetic compression will be adopted, based on the
expertise achieved at the SPARC high brightness
photoinjector presently under commissioning at Frascati
INFN-LNF Laboratories [1,2]. The use of
superconducting and exotic undulator sections will be
also exploited. In this paper we report the progress of the
collaboration together with start to end simulation results
based on a combined scheme of RF compression
techniques.
