The Istituto Nazionale Fisica Nucleare (INFN) is the Italian research agency dedicated to the study of the fundamental constituents of matter and the laws governing their behaviour. The Frascati National Laboratory (LNF) is the oldest and biggest INFN laboratory. LNF has a long-standing tradition in designing, building and operating high-energy particles accelerators but also in the use of synchrotron radiation.
The first Italian synchrotron radiation facility was built at the LNF and the experience in synchrotron activities was developed using for many years, at the beginning, the electron-positron collider, ADONE and nowadays DAΦNE, a high luminosity storage collider (0.51 GeV), designed for a broad programme in high-energy physics. DAΦNE provides intense synchrotron radiation beams, especially in the infrared region (IR), where the source intensity induces a large interdisciplinary interest from biological to geological applications. INFN operates, at the Frascati National Laboratory, the DAΦNE-Light synchrotron radiation facility with beamlines open external users. Over the last years, research activity at LNF attracted a sizeable amount of external users, with a relevant number of foreign scientists. Concerning the DAΦNE-Light Laboratory, an average of about 30 experiments per year have been performed by Italian, EU users in the framework of the INFN experiments, collaborations with Italian Universities and TARI (Transnational Access to Research Infrastructures).
