The core component of the Muon g-2 experiment at the Fermi National Accelerator Laboratory is a 50-foot superconducting electromagnet. UM physicist Breese Quinn is among the collaborators on the project that has made the most precise measurement ever of the movement of subatomic particles called muons. The magnet traveled through northeast Mississippi in 2013 on a 3,200-mile journey from New York to the underground laboratory in the suburbs of Chicago. Photo courtesy Fermilab
