Sanford Underground Research Facility

From Sanford Underground Research Facility, Nov. 24, 2020: Another series of upgrades to the Ross Shaft is under way at the Sanford Underground Research Facility. Crews are working to outfit the shaft with new cage and skip conveyances and have replaced thousands of feet of hoist cables. The work prepares the Ross Shaft for its role as the main travel way for upcoming excavation and construction of the Long-Baseline Neutrino Facility to support the Deep Underground Neutrino Experiment, the world’s flagship neutrino experiment, which is hosted by Fermilab.

From Black Hills Pioneer, Nov. 17, 2020: Thyssen Mining Company, one of North America’s largest mining companies, has signed a three-year contract to excavate space for the Long Baseline Neutrino Facility at Sanford Lab in South Dakota. The company plans to bring about 110 jobs for miners, operators, mechanics, electricians, engineers, and managers. Thyssen Mining is currently preparing office space in Lead, as well as getting personnel lined up, contracting with local vendors, and preparing equipment for the project.

Join Sanford Underground Research Facility for a virtual event on the international Deep Underground Neutrino Experiment, hosted by Fermilab. Three DUNE researchers will unpack the three major science goals of the experiment. The virtual lecture, “Deep Talks: Why DUNE?”, will be streamed on Thursday, Nov. 12, from 7-8 p.m. Central time. Join this event via Zoom webinar to answer polls and submit questions for our speakers, or watch it live on Sanford Lab’s Facebook page. Webinar space is limited, so…

Department of Energy officials have formally signed off on project completion for LUX-ZEPLIN, or LZ: an ultrasensitive experiment that will use 10 metric tons of liquid xenon to hunt for signals of interactions with theorized dark matter particles called WIMPs.

From Rapid City Journal, Aug. 6, 2020: Crews have begun installing a rock conveyor over U.S. Highway 85 in Lead, South Dakota, for the Long-Baseline Neutrino Facility. The conveyor will bring 800,000 tons of rock from the 4850 level of Sanford Underground Research Facility and deposit them into an open pit mining area that was excavated by the Homestake Gold Mine in the 1980s, making way for the international Deep Underground Neutrino Experiment, hosted by Fermilab.

From Sanford Underground Research Facility, Aug. 4, 2020: The most publicly visible milestone of the Long-Baseline Neutrino Facility’s pre-excavation work, a conveyor system, now extends over U.S. Highway 85 in Lead, South Dakota. Installation of the conveyor is one of a series of infrastructure strengthening projects undertaken to prepare the Sanford Underground Research Facility for its role as LBNF’s far site. Such projects lay the groundwork for the Deep Underground Neutrino Experiment, the most ambitious particle physics experiment on U.S. soil, hosted by Fermilab.

From Black Hills Pioneer, July 22, 2020: Since late 2019, work has been under way on the Long-Baseline Neutrino Facility conveyor system at the Sanford Underground Research Facility in South Dakota. The system will carry more than 800,000 tons of rock excavated from the site of the international, Fermilab-hosted Deep Underground Neutrino Experiment 4,850-feet below the surface. A major milestone for the project was met on July 20 as the 120-foot section of the truss, which will house the conveyor, was erected above the highway.

Construction workers have carried out the first underground blasting for the Long-Baseline Neutrino Facility, which will provide the space, infrastructure and particle beam for the international Deep Underground Neutrino Experiment. This prep work paves the way for removing more than 800,000 tons of rock to make space for the gigantic DUNE detector a mile underground.

From Gizmodo, May 18, 2020: Neutrino physics is a trek into the unknown, one that the United States physics community has chosen to pursue full-on. A flagship experiment called LBNF/DUNE will lead the search, in pursuit of answers that may take decades or more to find. Fermilab Deputy Director for Research Joe Lykken, DUNE spokesperson Ed Blucher, and DUNE scientists Chang Kee Jung and Elizabeth Worcester talk about how neutrinos will enhance our understanding of the universe.
