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.

Fermilab scientists have taken a major step in preparing for the Deep Underground Neutrino Experiment with a prototype particle accelerator. The 2×2 detector prototype has four liquid argon modules arranged in a square whereas the DUNE detectors will have 35 liquid argon time projection chambers, allowing scientists to track the movements of particles and determine their physical properties.

Physicists use large particle detectors filled with liquid argon to study neutrinos. Brazilian scientists discovered that a commercially available material can significantly reduce the amount of nitrogen in liquid argon, which improves the detection of neutrino interactions.

The award recognizes Marco Del Tutto for his work that enhances the capabilities of the Short Baseline Near Detector, the first stage of data collection along the Short-Baseline Neutrino experiment.

The cryogenic plant, to be installed a mile underground, will provide the cooling for two large liquid-argon neutrino detectors for the international Deep Underground Neutrino Experiment.

While studying at the University of Manchester, Green analyzed data from a liquid argon neutrino detector at Fermilab, developing new techniques to identify muons that would hint at new particles.

From the State University of Campinas, Unicamp (Brazil), March 13, 2023: This week Lia Merminga visited the State University of Campinas in São Paulo to attend a workshop on the purification of liquid argon. The event celebrated the achievements of the first phase of the LBNF/DUNE project and previewed the work to be carried out and the technologies to be developed in the next stage. Merminga stated the efforts of undergraduate and graduate students and the contributions of the university are essential to the success of DUNE.

The ICARUS detector, part of Fermilab’s Short-Baseline Neutrino Program, will officially start its hunt for elusive sterile neutrinos this fall. The international collaboration led by Nobel laureate Carlo Rubbia successfully brought the detector online and is now collecting test data and making final improvements.

Fermilab scientists are developing one of the most cold-tolerant robots ever made so they can monitor the interiors of particle detectors. The project has already garnered some interest from engineers at other research institutions, including NASA.

Fermilab contractors have successfully commissioned a system that will move 800,000 tons of rock to create space for the international Deep Underground Neutrino Experiment’s detectors in South Dakota. Excavation crews will transport the rock from a mile underground to the surface using refurbished mining infrastructure and the newly constructed conveyor system.
