From Popular Science: A new observatory under construction in China—the Jiangmen Underground Neutrino Observatory, or JUNO—plans to hunt the elusive neutrino with better sensitivity than ever before. Expected to be operational in 2024, this detector will not only be bigger, but also more sensitive to slight variations in neutrinos’ energies than any of its predecessors.

From Unicamp (upon opening the link, right click to translate to English): Last week, directors and scientists from Unicamp (the University of Campinas) and other research institutions visited Fermilab as part of the critical assessment by DOE on the progress of the international collaboration in building the large underground neutrino detector at LBNF. The University is responsible for the development and subsequent production of two sets of central equipment that will make up the laboratory to be installed in South Dakota 1,500 meters underground. One of the sets will be used to detect photons and the other to purify liquid argon.

Plans are moving ahead for the liquid nitrogen refrigeration system which will use liquid nitrogen to cool the 17,500 tons of liquid argon that will fill the neutrino detectors at the Long Baseline Neutrino Facility in the Sanford Lab. The system is expected to be built by 2026, and operational underground by the end of 2026 to support the installation of some detector elements, and the operations of the full facility starting in early 2028.

From Laser Focus World, Jan. 12, 2023: What does the future of detectors look like and what problems will they solve? Advances in novel detectors are working on some of the most elusive mysteries in science—from quantum teleportation to neutrinos and dark matter. The long-baseline neutrino detectors of DUNE are part of this line up of international detectors.

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.
