Deep Underground Neutrino Experiment Begins
- Fermilab says its top institutional priority is delivering a neutrino beam to DUNE by 2031; Director Norbert Holtkamp calls DUNE "the largest science project in our laboratory's history"[2]
- The beam is sent from Fermilab in Illinois to detectors at the Sanford Underground Research Facility in South Dakota, 1,300 km away and 1,490 m deep; the far detector is 70 kilotons of liquid argon in four modules[1][2]
- The PIP-II accelerator (expected complete by 2028) will drive the beam, designed at 2.4 MW[1][2]
- Goals: neutrino oscillations and CP violation, mass ordering, supernova neutrinos and proton decay; Hyper-Kamiokande is a competitor[1]
- Cost rose from under $2B to over $3B and the project has been described as "troubled"; in August 2024 a DUNE prototype detector at Fermilab detected its first neutrinos[1]

The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.

Fermilab's own July 2026 news post states its goal to "deliver a neutrino beam to DUNE at LBNF by 2031," matching the pin's stored estimated 2031 date directly from the experiment's home institution.[1]

Science's own title and March 29, 2022 publish date - "Trying to stay ahead of competition, U.S. pares down troubled $3 billion neutrino experiment" - describe DUNE being descoped years before the pin's 2031 estimate, offering older context rather than direct confirmation of the date; the page itself could not be fetched directly.

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
