Dune May 7 event

Fermilab marks major milestone for world-leading DUNE experiment

May 7, 2026

An event at the far site of the Deep Underground Neutrino Experiment at the Sanford Underground Research Facility in South Dakota marked the start of steel beams being lowered underground to house DUNE’s massive particle detectors. The event was attended by senior leaders from the Department of Energy; members of Congress; Fermilab, CERN and SURF leadership; and members of the local community, all of whom had the chance to sign one of the steel beams being installed.

Successful tests pave the way for Fermilab’s next-generation particle accelerator

July 22, 2021

This spring testing wrapped up at the PIP-II Injector Test Facility, or PIP2IT. The successful outcome paves the way for the construction of PIP-II, a new particle accelerator that will power record-breaking neutrino beams and drive a broad physics research program at Fermilab for the next 50 years.

Rock transportation system is ready for excavation of DUNE caverns

May 5, 2021

Fermilab contractors have successfully commissioned a system that will move 800,000 tons of rock to create space for the international Deep Underground Neutrino Experiment’s detectors in South Dakota. Excavation crews will transport the rock from a mile underground to the surface using refurbished mining infrastructure and the newly constructed conveyor system.
