The Project SPARC (Sorgente Pulsata e Amplificata di Radiazione Coerente), proposed by a collaboration among ENEA-INFN-CNR-Universita' di Roma "Tor Vergata" -INFM-ST, was recently approved by the Italian Government and will be built at LNF of INFN. The aim of the project is to promote an R&D activity oriented to the development of a coherent ultra-brilliant X-ray source in Italy. This collaboration has identified a program founded on two main issues: the generation of ultra-high peak brightness electron beams and of resonant higher harmonics in the SASE-FEL process. 353 2003 Particle Accelerator Conference /home/httpd/docserver/releases/20080613005430/public/paper/file/12/alesini_2003_0524.pdf alesini_2003_0524.pdf 3 12 3 2003 IEEE 524 2007-10-19T15:26:12-07:00 2003
