FRIB construction: Workers place concrete on March 3, 2015, at the Facility for Rare Isotope Beams, under construction at Michigan State University. The March 3 placement was the largest of the entire FRIB Project; workers placed nearly 3,600 cubic yards of concrete in the linear accelerator tunnel, enough to fill an Olympic-sized swimming pool. The Facility for Rare Isotope Beams is a new scientific user facility for nuclear science, funded by the U.S. Department of Energy Office of Science and operated by Michigan State University.
