One critical aspect in designing a space mission is the assessment of the level of radiation damage to the equipment that
one can expect during the course of the mission. The radiation environment in L2 orbit, however, has not been studied as
extensively as in the Low Earth Orbit case. Fluka is a Montecarlo software developed by CERN and INFN and
extensively used in high energy experimental physics and engineering, shielding, detector and telescope design, and
cosmic ray studies. In this paper, we make use of FLUKA to model the geometry of the structures surrounding the
detector, in order to analyze the mitigation strategy (i.e.: shielding of the detector assembly) in a well defined case (the
Euclid-NIS instrument, which is in its early design phase). By using a realistic cosmic ray spectrum and composition, we
analyze the resulting dose of ionizing and non-ionizing radiation on the Euclid-NIS detectors, and other effects.

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 INFNLNF
Laboratories. 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.
