From Público, Nov. 24, 2020: Homestake fue la mayor y más profunda mina de oro de de Norteamérica hasta que se cerró en 2002 tras 125 años de funcionamiento. Este remoto lugar de Dakota del Sur se convirtió oficialmente en 2007 en un laboratorio subterráneo de física fundamental, aunque ya mucho antes se habían instalado en sus profundas cavernas algunos experimentos, incluido uno que mereció el premio Nobel. Ahora se anuncia la nueva etapa para convertir la mina en sede del megaproyecto científico más importante de las últimas décadas en Estados Unidos, el Long-Baseline Neutrino Facility, dedicado a estudiar las partículas fundamentales llamadas neutrinos.
From Sanford Underground Research Facility, Nov. 24, 2020: Another series of upgrades to the Ross Shaft is underway 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.
This month, Thyssen Mining Inc. was awarded the contract to excavate the gigantic caverns for Fermilab’s Long-Baseline Neutrino Facility. Excavation crews will drill, blast and remove approximately 800,000 tons of rock to create the underground space for LBNF. When complete, the facility will house the enormous particle detector for the international Deep Underground Neutrino Experiment, hosted by Fermilab.
All summer long, progress on preparing the Fermilab site for the construction of the Long-Baseline Neutrino Facility has been proceeding at a healthy clip. Now, as summer winds down, that site prep is nearing completion.
From Science, Oct. 2, 2020: As U.S. particle physicists start to drum up new ideas for the next decade in a yearlong Snowmass process they have no single big project to push for (or against). Physicists have just started to build the current plan’s centerpiece: The Long-Baseline Neutrino Facility at Fermilab will shoot particles through 1,300 kilometers of rock to the Deep Underground Neutrino Experiment in South Dakota. Fermilab Deputy Director of Research Joe Lykken and Fermilab scientist Vladimir Shiltsev comment on other possible pursuits in high-energy physics.
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 underway 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.
