At Fermilab, the magnet will become part of a machine designed to store elementary particles, called muons, which are similar to electrons but heavier. Inside the magnetic field of the ring, a muon’s spin “wobbles” by a predicted amount, says Hogan Nguyen, a scientist at Fermilab who has the Tolkienesque title “manager of the ring.” Scientists at Brookhaven and Fermilab, as well as other institutions worldwide, want to measure this wobble, which is affected by the presence of subatomic particles such as bosons, to detect undiscovered particles and forms of energy in the universe. “This experiment has the potential to open doors to new types of physics,” says Andre Salles, a Fermilab spokesman.
