High-Density Concrete Used in NSLS-II Construction

January 27, 2010

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.
