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.

From Yale University, Jan. 22, 2021: For his new piece of music, “MicroBooNE,” David Ibbett, Fermilab’s first composer-in-residence, collaborated with physics professor Bonnie Fleming through a series of discussions about the science behind the experiment that inspired the composition. The neutrino-inspired piece premiered on Dec. 8, 2020, as part of the Fermilab Arts and Lectures Series.

From Oak Ridge National Laboratory, Jan. 26, 2021: The COHERENT particle physics experiment at Oak Ridge National Laboratory has firmly established the existence of a new kind of neutrino interaction. To observe this interaction, scientists used CENNS-10, a liquid argon detector built at and on loan from Fermilab.

In this 5-minute video, Nobel laureate Carlo Rubbia explains why mysterious particles called neutrinos could be the key to understanding the nature of the universe. He talks about the search for a fourth type of neutrino and why the universe would not exist without neutrinos. He describes how scientists aim to unveil the secrets of the neutrino with the ICARUS and DUNE neutrino experiments, hosted by Fermilab. He recalls why early in his career he chose liquid argon as his material of choice to collect information about neutrino interactions with matter.

From Gasworld: Jan. 1, 2019: Trade publication Gasworld published a three-page cover story on DUNE, focusing on the experiment’s use of liquid argon. Print edition only.
