NuMI

A large silver- and copper-colored metallic structure, with four silver "stripes" forming a rounded rectangle and a diamond at the bottom with a cooper circle in the center, stands in the center of the photo.

The Fermilab particle accelerator complex set a record beam power earlier this year, thanks to the high-quality work of numerous teams and individuals. The successful completion of the NuMI 2020 shutdown work prepared the target facility for this achievement.

Neutrinos can easily make their way through the earth and rock between Batavia and a half-mile-deep mineshaft in Soudan, Minnesota, but physicists in the NuMI (Neutrinos at the Main Injector) experiment need the help of a $30.5-million, 20-month excavation effort to create some 4,000 feet of tunnels and other underground experimental areas at the U.S. Department of Energy’s Fermi National Accelerator Laboratory.
