A mile underground in South Dakota, construction crews have worked diligently to carve out an extensive network of caverns and tunnels that one day will house a huge neutrino experiment. Their efforts have paid off: With almost 400,000 tons of rock extracted from the earth, the excavation has reached the halfway point.

From the Rapid City Journal, Jan. 12, 2023: An interview with Fermilab project manager Joshua Willhite on the excavation of the caverns for the Deep Underground Neutrino Experiment (DUNE) being built under the Black Hills of South Dakota at SURF. Willhite is a mechanical engineering graduate of the South Dakota Mines university who spoke with him about his love of engineering and how the program at SD Mines led to his work on DUNE. This article is an adaptation of the South Dakota Mines story that published on Jan. 10.

The international LBNF/DUNE team with its partners recently tested the logistics of shipping and handling the large detector components that will make up the far-site detector of the Deep Underground Neutrino Experiment. On Wednesday, Nov. 2, personnel at the Sanford Underground Research Facility successfully lowered a 25-foot-long detector component for DUNE a mile underground. This was a full-scale prototype assembled and tested in Europe, then shipped from CERN to South Dakota. DUNE will ship about 150 of these components to South Dakota to build the first neutrino detector module of the Deep Underground Neutrino Experiment.

From Physics Today: Snowmass 2022 this past July took place over 10 days with almost 1,200 people participating online and in person at the University of Washington. It involved 511 white papers spanning 10 “frontier” areas. This once-a-decade meeting also reaffirmed support for completing the Deep Underground Neutrino Experiment (DUNE) and the affiliated Long-Baseline Neutrino Facility to carry our DUNE’s science goals.

Excavation of the large caverns for the Long-Baseline Neutrino Facility is in full swing. Over a third of the whopping 800,000 tons that need to be extracted from a mile underground 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.
