US turns gold mine into giant fridge to study ghost-like neutrinos

Scientists in the United States are undertaking a major engineering project to build massive, super-cooled containers to hold over 15,000 tons of liquid argon at minus 303 degrees Fahrenheit for the Deep Underground Neutrino Experiment (DUNE). This flagship physics experiment aims to study elusive neutrinos by immersing detectors in huge baths of cryogenic liquid argon deep underground at the Sanford Underground Research Facility in South Dakota. Being located a mile underground helps shield the detectors from cosmic rays, allowing for precise measurements of neutrinos sent from Fermilab in Illinois, as well as neutrinos from astrophysical sources like the sun or supernovae. DUNE is considered the most sensitive experiment designed to explore the origins of the universe through neutrino properties. The experiment involves installing multiple multi-kiloton detector modules using liquid-argon time-projection chamber (LArTPC) technology, each housed in enormous cryostats roughly the size of five Olympic swimming pools. These cryostats, designed by G
