1. 3rd LI2FE Meeting, INFN-LNF, 11/3/2010 LI 2 FE Laboratorio Integrato Interdisciplinare con Fotoni ed Elettroni Luca Serafini - INFN/MI on behalf of LI 2 FE Collaboration Board LI 2 FE comprises: SPARC Photo-injector and beam lines, FLAME laser and beam lines, SPARC undulator, associated advanced instrumentation, THE PEOPLE EXPERTISE LI 2 FE constitutes: a multi-disciplinary integrated research infrastructure based on a twin system of fs-class synchronized high brightness e - beams and high intensity laser beams

2. High Brightness Electron Beams (ps to fs bunch length) High Intensity Laser Beams (20-100 fs pulses) SPARC (Sorgente Pulsata e Amplificata di Radiazione Coerente) and PLASMONX (PLasma Acceleration @ Sparc & MONochromatic X-rays) Unique worldwide at these level of combined beam performance Synchronized to fs level 3rd LI2FE Meeting, INFN-LNF, 11/3/2010

3. Development of a wide inter-disciplinary research program, combining high brightness high rapidity electron beams (drive plasmas at 7.10 19 cm -3 => TV/m) with high intensity ultra-short laser pulses (4.10 18 cm -3 => 250 GV/m), leading in turns to production of a variety of advanced beams of FEL/THz radiation, advanced beams of X/  rays (thanks to a photon- electron collider at 10 35 cm -2 s -1 luminosity), protons/light ions, and potentials for polarized positrons and neutrons of unique characteristics.
