Particle beams are once again zooming around the world’s most powerful particle accelerator—the Large Hadron Collider—located at the CERN laboratory near Geneva, Switzerland. On November 20 at 4:00 p.m. EST, a clockwise circulating beam was established in the LHC’s 17-mile ring.

Officials at the Department of Energy’s Fermi National Accelerator Laboratory are seeking nominations from the local community for members to serve on a new Community Advisory Board.
