DUNE at LBNF

One third of LBNF excavation complete

Over a third of the whopping 800,000 tons of rock that need to be extracted from a mile underground to create the space for the Long-Baseline Neutrino Facility have been removed. 

When finished, the underground facility will cover an area about the size of eight soccer fields and provide space for the international Deep Underground Neutrino Experiment.

This 2-minute animation shows the planned layout of the new facility:

The drill-and-blast phase will be complete in the fall of 2023. More information about the on-going excavation is in this article published by Fermilab.
