DAΦNE (Double Annular Φ-Factory for Nice Experiments) is a world-class electron-positron collider at the Frascati National Laboratories of INFN (LNF-INFN) in Italy.
The DAΦNE accelerator complex includes a double ring lepton collider working at the c.m. energy of the φ-resonance (1.02 GeV) and an injection system.
The two independent rings, each ∼ 97m long, share two 10 m long interaction regions.

Particle and Nuclear Physics

The SIDDHARTA-2 experiment aims to perform the first measurement of the kaonic deuterium exotic atom, by measuring the X rays transitions to the fundamental 1s level. The setup consists of advanced spectroscopic Silicon Drift Detectors (SDD), two veto-systems and a trigger to enhance the signal/background ratio.

The Positron Annihilation into Dark Matter Experiment (PADME) aims to search for the production of a Dark Photon (DP) in the process e+ e- → A'γ, by using the 550 MeV positron beam provided by the DAΦNE linac and interacting with a Carbon target.

Beam Test Facility

The DAΦNE linac Beam Test Facility (BTF), is a beam transfer-line from the DAΦNE linac, capable of providing up to 50 bunches per second of electrons/positrons with 800/550 MeV maximum energy and a variable bunch width from 1.5 to 40 ns.
