When the NSLS-II is running, electrons traveling at nearly the speed of light and forced by magnets around a circular storage ring will produce energy in the form of light known as synchrotron radiation. Lead and concrete shielding around the injector and storage rings and along the beamlines will provide protection against these photons and neutrons, and radiation exposure to personnel working on the NSLS-II floor will be quite low. In this video, BNLs lead structural engineer Tom Joos describes how higher-density concrete can be used where shielding is particularly necessary.
One of ten national laboratories overseen and primarily funded by the Office of Science of the U.S. Department of Energy (DOE), Brookhaven National Laboratory conducts research in the physical, biomedical, and environmental sciences, as well as in energy technologies and national security. Brookhaven Lab also builds and operates major scientific facilities available to university, industry and government researchers. Brookhaven is operated and managed for DOE's Office of Science by Brookhaven Science Associates, a limited-liability company founded by the Research Foundation for the State University of New York on behalf of Stony Brook University, the largest academic user of Laboratory facilities, and Battelle, a nonprofit applied science and technology organization.
