Abstract:
Two beamlines for the use of InfraRed Synchrotron Radiation (IRSR) are presently working in Italy, at the ELETTRA storage ring in Trieste, and at the collider DAFNE in Frascati. A third facility, SPARC in Frascati, has been equipped for the extraction of Terahertz radiation with the aim to perform pump-probe time-domain experiments. Here we describe those apparata and we review the main results that the Italian groups have obtained therein, in recent years, in solid-state physics. We also describe the experiments performed in collaboration with the storage ring BESSY in Berlin, for the exploitation of Coherent Synchrotron Radiation, and the terahertz beam line recently implemented at SPARC, the Free Electron Laser of Laboratori Nazionali di Frascati 1. The beamline SINBAD at DAFNE and the high-pressure measurements SINBAD (Synchrotron Infrared Beamline At DAFNE) was the first InfraRed Synchrotron Radiation (IRSR) beamline built in Italy, under a collaboration between the Istituto Nazionale di Fisica Nucleare (INFN) and the Università di Roma La Sapienza. SINBAD collects in a parasitic regime the radiation emitted by a bending magnet of DAFNE, an electron-positron collider that is designed to work at 0.51 GeV with a beam current of more than 1 A in each ring. Due to such a high current, the infrared extracted from DAFNE is more brilliant than that of a black body by more than one order of magnitude at 100 cm-1. The front end of SINBAD collects a solid angle of 18 x 45 mrad2 and the plane extraction mirror is placed at about 4,5 m from the source located along the bending magnet arc.
