ISLAMABAD-U.S. Department of Energy (DOE) Under Secretary for Science Paul Dabbar, leaders from DOE’s Brookhaven National Laboratory (Brookhaven Lab) and Thomas Jefferson National Accelerator Facility (Jefferson Lab), and elected officials from New York State and Virginia today commemorated the start of the Electron-Ion Collider project. The event was an opportunity for in-person and virtual speakers to voice their support for this one-of-a-kind nuclear physics research facility, which will be built at Brookhaven Lab by a worldwide collaboration of physicists over the next decade. The 2.4-mile-circumference particle collider will act as a high-precision sub-atomic “microscope” for exploring the innermost three-dimensional structures of protons and larger atomic nuclei.
