Fermilab is building a new linear accelerator! 🤩 In this video, take a behind the scenes look inside the tunnel that will house the new 800-million-electronvolt linac. The Proton Improvement Plan-II is an essential enhancement to the Fermilab accelerator complex, powering the world’s most intense high-energy neutrino beam on its journey from Illinois to the Deep Underground Neutrino Experiment at Sanford Underground Research Facility. DUNE scientists will use neutrinos to answer some of the mos

The PIP-II project is an essential upgrade of Fermilab’s particle accelerator complex and includes the construction of a 215-meter-long linear particle accelerator. It is the first U.S. particle accelerator project with significant contributions from international partners. Research institutions in France, India, Italy and the UK will build major components of the new particle accelerator. PIP-II will become the new heart of the Fermilab accelerator complex. Its high-intensity proton beams will
