TA-LNF is the acronym for Transnational Access (TA) to the Research Infrastructure Frascati National Laboratories (LNF) of Istituto Nazionale di Fisica Nucleare.

The objective of TA-LNF is to provide researchers from European Member States and Associated Countries with free access to the facilities of LNF. The external users take advantage of infrastructural, logistical, technological and scientific support (including travel and subsistence).

The Frascati National Laboratories (LNF), founded in 1955, are the oldest and biggest Laboratories of INFN and are devoted to fundamental research in nuclear and subnuclear physics. They were built to host the electron synchrotron, which at that time, with its energy of 1.1 GeV, represented a world record. Around 1960, a new accelerator concept was conceived and demonstrated in Frascati: a colliding-beam accelerator. All modern elementary particle storage rings descend from that first prototype, ADA (Anello Di Accumulazione). Immediately afterwards, a large electron-positron collider (ADONE) was designed, built and brought to operation in 1969. ADONE had a c.m. energy of 3 GeV and held the world record in energy and its experiments paved the road to the understanding of particle physics. One of its main achievements was the observation of the abundant production of multihadron events, which later led to the discovery of a new degree of freedom of the quarks: the color.

The LNF cover an area of 140000 m2 and are located about 20 km from the centre of Rome. They can be easily reached from Rome by car, by bus and by train. Presently, LNF hosts DAΦNE, a high luminosity e+ e- collider at 1.02 GeV c.m. energy, (φ-factory), which delivers an antikaon beam from φ-decays to the SIDDHARTA-2 experiment for precision kaonic atoms measurements. Electrons and positrons are provided by the DAΦNE linac. A new experiment, PADME, aims to search for the “dark photon” by detecting the products of annihilations of the linac positrons on a fixed target. A Beam Test Facility (BTF) utilizing the linac is available for calibration purposes.
