Construction of the LBNF/DUNE Caverns – South Dakota (USA)

by James Rickard (Arup)


12 October 2023


10:30 am



This talk will present the Long Baseline Neutrino Facility Far Site (LBNF) project is located deep underground at the Sanford Underground Research Facility (SURF) in Lead, South Dakota. SURF is a dedicated underground scientific facility located at the former site of the Homestake Gold Mine. The new LBNF facility will house the Deep Underground Neutrino Experiment (DUNE), an international flagship experiment which will seek to enhance our understanding of the universe, the matter which comprises it, and ultimately the role that the neutrino plays in all of it. The project is funded by the US Department of Energy and managed by the Fermi Research Alliance. Fermilab is the host laboratory for DUNE, in partnership with a wider, global consortium of agencies and institutions. Four massive, liquid argon filled particle cryostat detectors will be sited nearly one mile underground at SURF and be on the receiving end of one of the world’s most intense neutrino beams emitted from the LBNF Near Site facility on the grounds of Fermilab in Batavia, Illinois. The Long Baseline Neutrino Facility Far Site in Lead, South Dakota is currently under construction and involves drill and blast excavation of the largest and deepest caverns in North America.

About the Speaker:

James Rickard is currently seconded to Fermilab and is full time on site in Lead, South Dakota, USA, supervising the Cavern Excavation for the Long-Baseline Neutrino Facility/Deep Underground Neutrino Experiment funded by The Department of Energy.
