Frascati at the Center of the New European Generation of Compact Accelerators With the publication of the Technical Design Report (TDR), EuPRAXIA@SPARC_LAB takes a decisive step toward the realization of the world’s first user facility based on plasma acceleration. The project, led by the INFN National Laboratories of Frascati, defines in detail the construction of a compact 1 GeV accelerator that integrates X-band RF technology and beam-driven Plasma WakeField Acceleration (PWFA), with the goal of realizing a Free Electron Laser operating in the water window, beamline AQUA in the figure, a strategic spectral region for applications in biology, materials science, and life sciences. The project is funded by the Italian Ministry of University and Research, by INFN, and by a contribution from the Lazio Region aimed at the realization of an industrial applications beamline named ARIA. The TDR is the result of an extensive collective effort: 176 signatories from 28 institutes contributed to the definition of the project, demonstrating the strength of a highly integrated national and international scientific network. Alongside the Accelerator and Technical Divisions of LNF, which played a central role in the machine and infrastructure design, fundamental contributions were provided by CNR, Elettra Sincrotrone Trieste, ENEA, Sapienza University of Rome, the University of Milan, and the University of Rome Tor Vergata. EuPRAXIA@SPARC_LAB represents one of the two European pillars of the EuPRAXIA project, included in the ESFRI roadmap, and provides a concrete demonstration of the possibility of building more compact, energy-efficient, and scalable accelerators. The adopted acceleration …

The new Chief Editor of Nuclear Physics A has selected, among the journal’s most significant articles of recent years, the study conducted by the SIDDHARTA‑2 collaboration on the X‑ray transitions of kaonic helium‑4, confirming the role of the INFN Frascati National Laboratory and of DAΦNE as a top‑level infrastructure for exotic‑atom physics.

The Beam Test Facility (BTF) at LNF will be open to external users during the following period: April 13, 2026 (week 15) – June 29, 2026 (week 27).

A significant step forward for the Mu2e experiment at Fermilab: the electromagnetic calorimeter, one of the fundamental components of the experiment, has been completed and installed in the experimental hall.

On September 23, the Circolo Cittadino in Latina hosted the MAGIC (MAgnetic Gadgets for Innovative Creations) awards ceremony. This initiative has been promoted by the Sezione Meccatronica of Unindustria and developed with the technical-scientific partnership of the Frascati National Laboratory in collaboration with the ITS Meccatronico del Lazio Academy.

As part of the MSCA Staff Exchange programme, the European Commission has recently selected the NEMESIS project (Neutron Experiments join Muon Experiments for Synergy in Investigation and Search for new physics) for funding. This is a consortium made up of research institutions and industrial partners, led by the National Laboratory of Frascati (LNF) of INFN.
