neutrinos

A detector in the Mediterranean discovered a cosmic neutrino carried 30 times more energy than any neutrino observed to date. Fermilab’s Bryan Ramson weighs in the new discovery.

Particle accelerator beams can create significant damage to the targets used to generate particles for experiments. Researchers are designing targets to withstand material degradation from radiation damage, shock from thermal expansion and material fatigue — all caused by accelerated protons.

A successful test delivers DUNE steel beam a mile underground at Sanford Underground Research Lab in Lead, South Dakota.

Now that the excavation of 800,000 tons of rock from the Sanford Underground Research Facility is complete, LBNF-DUNE teams are working on the the far detector in South Dakota and the near detector at Fermilab in Illinois. The science collaboration includes more than 35 countries and DOE’s Office of Science is supporting the LBNF-DUNE to help answer some of physics’ biggest questions.

Argonne recently hosted the 25th international workshop on Neutrinos from Accelerators attended by global experts in high energy physics. Fermilab Director, Lia Merminga was the keynote speaker to nearly 200 theorists and experimentalists attending NuFact who are investigating the elusive neutrino.

Now that the excavation of the LBNF-DUNE project is complete, science and engineering teams are developing the detectors and systems DUNE will use to study neutrinos. The launch of LBNF/DUNE will bring a new era in understanding neutrinos and knowing more about our universe as a whole.

The 2×2 detector has captured its first neutrino interactions at Fermilab with help from scientists at SLAC. The prototype neutrino detector will help fine-tune a full-size version of the DUNE Near Detector Liquid Argon detector and will capture up to 10,000 neutrino interactions per day.

At the beginning of the universe, equal amounts of matter and antimatter collided and there should have been nothing left. Yet, matter won out but why? Fermilab scientist Jessica Esquivel talks with NPR about the mysteries of neutrinos for answers.

After years of preparation, the first neutrinos have been observed by the Short-Baseline Near Detector collaboration. The data SBND collects will expand our knowledge of how neutrinos interact with matter and will be used to search for evidence of new physics.

The New York Times reports on LBNF/DUNE. When DUNE operations begin, the research results could a major gap in scientists’ understanding of the universe and return the United States to its former position at the center of particle physics.
