The aim of the SPARC project is to promote an R&D activity oriented to the development of a high brightness photoinjector and to drive SASE-FEL experiments. It has been proposed by a collaboration among ENEA-INFN-CNR-Universita` di Roma Tor Vergata-INFM-Sincrotrone Trieste and funded by the Italian Government with a 3 year time schedule. The machine will be installed at Laboratori Nazionali Frascati, inside an existing underground bunker. It is comprised of an rf gun driven by a Ti:Sa laser to produce 10-ps flat top pulses on the photocathode, injecting into three SLAC accelerating sections and finally in a segmented undulator composed by six variable gap sections. A number of experiments ranging from the injector optimization and on rf compression techniques, emittance degradation due to CSR effects, FEL physics including harmonic generation and HGHG seeding are foreseen.
