SBND

Physicists take on the mystery of the missing (and extra) neutrinos.

Researchers from more than 50 countries collaborate with Fermilab to develop state-of-the-art technologies and solve the mysteries of matter, energy, space and time. Take a look at 10 ways Fermilab and its partners advanced science and technology in 2021.

From Pesquisa, November 2020: The FAPESP scientific director shares how he encouraged behaviors that helped improve research in São Paulo. With FAPESP encouragement, researchers in Brazil have held leadership positions in international collaborations, including in a photon detection system called Arapuca. Arapuca is a technology used in Fermilab’s Short-Baseline Near Detector and a baseline technology for the international Deep Underground Neutrino Experiment, hosted by Fermilab.

From CERN Courier, July 7, 2020: A new generation of accelerator and reactor experiments is opening an era of high-precision neutrino measurements to tackle questions such as leptonic CP violation, the mass hierarchy and the possibility of a fourth “sterile” neutrino. These include the international Deep Underground Neutrino Experiment, hosted by Fermilab, and Fermilab’s NOvA and Short-Baseline Neutrino programs.

From the University of Bern, May 2020: The University of Bern and Fermilab partner on three neutrino projects aimed at a thorough study of some postulated properties of the ghostly particle: MicroBooNE, SBND and the Deep Underground Neutrino Experiment, the latter to be considered the world’s ultimate neutrino observatory.

Fermilab and the University of Bern in Switzerland have signed an agreement to develop detector components for the laboratory’s neutrino experiments. The agreement is the first of its kind between Fermilab and a Swiss university.

From Science, Aug. 8, 2019: Fermilab physicists are resurrecting a massive particle detector by lowering it into a tomblike pit and embalming it with a chilly fluid. In August, workers eased two gleaming silver tanks bigger than shipping containers, the two halves of the detector, into a concrete-lined hole. Hauled from Europe two years ago, ICARUS will soon start a second life seeking perhaps the strangest particles physicists have dreamed up, oddballs called sterile neutrinos.

For over two decades, Spanish institutions have been collaborating with Fermilab. From the Tevatron era to the lab’s current neutrino experiments, Spain has made important contributions.

From Syracuse University, Dec. 20, 2018: Collaborators at Syracuse University are contributing components for Fermilab’s Short-Baseline Near Detector, one of three particle detectors in the Short-Baseline Neutrino program.

The upcoming Short-Baseline Near Detector at Fermilab continues scientists’ search for evidence of a hypothetical particle, the sterile neutrino. Collaborators around the world are participating in the detector’s construction. Its first critical components recently arrived from partner institutions. When complete, SBND will be the third and final detector in Fermilab’s Short-Baseline Neutrino Program.
