NSLS-II stores 25 milliamps of current
"This achievement was made possible by the hard work of our staff, the Laboratory, the Department of Energy, and our many colleagues who have helped to shepherd the project to this milestone," said Steve Dierker, Associate Laboratory Director for Photon Sciences. "Together we are looking forward to completion of the project and an exciting science program for our user community."
When completed, NSLS-II will be a state-of-the-art, medium-energy electron storage ring that produces x-rays up to 10,000 times brighter than the original NSLS, which started operating at Brookhaven Lab in 1982 and is shutting down at the end of September 2014.
NSLS-II construction began in 2009, with a $912-million budget from the U.S. Department of Energy Office of Science. Construction has passed through distinct phases, starting with conventional construction of the ring building and laboratory-office buildings; installation of the accelerator and beamlines; now commissioning of the injection system, which consists of a linear accelerator, the booster, transport lines and a storage ring; followed by commissioning of an initial suite of beamlines for early science.
