Elettra Sincrotrone Trieste is a multidisciplinary international laboratory of excellence, specialized in generating high quality synchrotron and free-electron laser light and using it in materials science. The main assets of the research centre are two advanced light sources, the electron storage ring Elettra and the free-electron laser (FEL) FERMI, continuously (H24) operated, supplying light of the selected "colour" and quality to more than 30 experimental stations.

Excellence: Unique among the only five FEL sources currently operating in the ultraviolet and soft x-ray range worldwide, FERMI has been developed to provide fully coherent ultra-short (10-100 femtosecond) pulses with a peak brightness ten billion times higher than that made available by third-generation light sources. FERMI is opening unique opportunities for exploring the structure and transient states of condensed matter, soft matter and low-density matter using a variety of diffraction, scattering and spectroscopy techniques. Presently, five beamlines are operational at FERMI: one devoted to elastic and inelastic scattering (, one to diffraction and projection imaging (, one to low-density matter studies (, one to the study of transient magnetic states of matter ( and one to THz spectroscopy (
