The public is being offered tours of a nuclear science facility that's being built at Michigan State University.
A free open house is scheduled 1 p.m. to 4 p.m. on Aug. 20.
The Lansing State Journal reports tours will be available of the 570-foot-long underground tunnel where beams of charged particles will travel at half the speed of light before colliding.
During the self-guided tours, the public also will be able to tour the Facility for Rare Isotope Beams' surface structure and the nearby National Superconducting Cyclotron Laboratory.
Scientists will be on hand to offer information.
Demonstrations also are planned.
Also known as FRIB, the East Lansing facility scheduled to be completed by 2022 will help scientists make discoveries about the properties of rare isotopes.
