The Deep Underground Neutrino Experiment (DUNE) in the USA aims to unravel the secrets of neutrino elementary particles. They already played an important role in the early stages of the universe, as the University of Bern announced in a press release on Wednesday.
For the experiment, a neutrino beam was sent from the particle physics research center Fermilab in Chicago to South Dakota, 1300 kilometers to the west. By taking measurements at nearby and distant sources, the researchers want to find out how the particles change type on their journey, the statement continued. This phenomenon is known as neutrino oscillation. The counterpart of neutrinos, antineutrinos, will also be investigated.
A detector like the one at the University of Bern can detect an intense stream of neutrinos and antineutrinos in 3D images. Nothing like this has ever been built or tested before, it was reported. According to Michele Weber, Director of the Laboratory for High Energy Physics (LHEP) and head of the Bernese DUNE group, the successful neutrino detection now allows the detector to be finalized and enlarged.
After maintenance work, the neutrino beam at Fermilab is to be put back into operation from fall 2024. The prototype will then record around 10,000 images per day for several months.
