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 Scientific American, July 2020: Evidence for the existence of a sterile neutrino is compelling, but the idea that certain experiments might be detecting a fourth neutrino remains controversial. Projects around the world seek to settle the matter, including Fermilab’s Short-Baseline Neutrino program.
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.
This assembly and transport frame is patiently awaiting completion in the DZero Assembly Building. When completed, it will enable the support and transport of the SBND detector to its final destination, the Short-Baseline Neutrino Near Detector hall, 110 meters from the Booster Neutrino Beam target. SBND is one of the three particle detectors that make up the Short-Baseline Neutrino program at Fermilab. A 4-by-4-by-5 meter detector, it will consist in a tank filled with liquid argon and a series of anode plane assemblies.
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.
