LBNF completes upgrade to far site's underground

Oct 01, 2019 · The LBNF project recently completed an upgrade of the Oro Hondo fan, replacing its variable-frequency drive, or VFD. The Oro Hondo fan is the main ventilation fan for the underground facility and is located on the surface along Kirk Road near Lead, South Dakota. This upgrade, completed with the support of Sanford Lab and four local contractors

Introduction - Fermilab

The progress with LBNF is very visible at SURF and is exciting. Additionally, the committee recognizes the challenges involved in maintaining the momentum in excavation in the context of a changing DOE view of CD approval strategy. Overall, DUNE as a collaboration continues to grow adding countries, institutions, and

DUNE at LBNF

LBNF provides the enormous caverns and cryogenics infrastructure for the DUNE detector deep underground at Sanford Lab. This includes the excavation of 800,000 tons of rock. It will also build structures at Fermilab to send neutrinos through stone and earth to South Dakota — no tunnel needed. World record beam.
