| Description | SPARC_LAB is an inter-disciplinary laboratory in operation at INFN National Laboratories in Frascati (Italy) with features unique in the world. Born from the integration of a last generation photo-injector, able to produce electron beams up to 200 MeV energy with high peak current (> 1 kA) and low emittance (<2 mm-mrad), with a high power laser (> 200 TW) able to produce ultra-short pulses (<30 fs), SPARC_LAB has already enabled the development of innovative radiation sources and the testing of new techniques for particle acceleration using lasers. In particular a Free Electron Laser has been commissioned (SASE coherent radiation tunable around 500 nm and down to 40 nm with harmonic generation) and new regimes of operation (single spike, two colors) have been observed; a source of narrow band (<30%) and high energy (> 10 μ J) THz radiation has been tested and electrons have been accelerated up to 100 MeV in 4 mm long plasma wave excited by the high power laser FLAME. An experiment of light ions acceleration through laser interaction with thin metal targets is also underway. SPARC_LAB is also an accelerator test facility in the framework of the European collaborations ELI, EUROFEL and EURONNAC. During 2014 the beams of electrons and photons will be synchronized at the scale of tens of fs, an essential requirement for the on going experimental program aimed at creating a source of X-rays by means of back-scattering Thomson, and at the investigation of new ultra-compact acceleration techniques (> 1 GV/m) based on external injection of high quality electron beams in a plasma wave. SPARC_LAB in open also to external users and its activities are continuously monitored by a dedicated International Program Advisory Committee, the LNF Scientific Committee and the INFN Scientific Board CSN5. |
