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 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.

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.

The LBNF Construction Zone has been updated to allow easier access to MI-10 and MI-20; however, Indian Creek road between MI-10 and MI-20 remains closed to thru traffic — this means vehicles and pedestrians. This is an active construction zone. Access to this area requires PPE and check-in with LBNF construction coordinators. To access MI-20, you must drive the long way around the Main Injector. Safety is our priority.

The PIP-II team has installed two webcams for documenting the construction of the conventional facilities to house the PIP-II accelerator and related work. Watch the buildings go up in real time, or have fun looking at time-lapse videos of the site development and construction. The webcams are located on the 16th floor of Wilson Hall, looking east, and the Fermilab Main Ring infield, looking west-northwest. Steve Dixon of the PIP-II Project team led the webcam installation effort.
