Installation of final magnet girders
Brookhaven Lab's National Synchrotron Light Source II (NSLS-II), under construction since 2009, will be a new state-of-the-art, medium-energy electron storage ring (3 billion electron-volts), designed to deliver world-leading intensity and brightness. It will produce x-rays more than 10,000 times brighter than our current NSLS when it begins operating in 2015.
In January, the last of 150 magnet girders was installed in the storage ring of the new Light Source capping off a tremendous year-long effort in which 843 magnets were safely delivered, tested, and installed.
The magnets traveled to the Lab from across the globe. They were supplied by ring magnet vendors based in six countries that include New Zealand, Russia, Denmark, the U.S., China, and the United Kingdom.
As the magnets arrived at the Lab, they were thoroughly tested and installed on girders, which were placed into the NSLS-II ring tunnel. During the early part of 2012 two girders were being installed per week; as the year ended, that rate was three to five per week. These installations required painstaking precision to align the magnets properly. If the magnets are misaligned by even a tenth of a millimeter, the error is amplified and the orbit of the beam will be shifted by 10 times as much. The electron beam whips around the storage ring at practically the speed of light, and because the beam is so tightly focused, it is also extremely sensitive to small obstacles. At that velocity, if the beam encounters even the smallest of bumps, it can spiral outward off course and dissipate.
Brookhaven's National Synchrotron Light Source II (NSLS-II) was recently awarded a LEED Gold rating by the U.S. Green Building Council. NSLS-II is Brookhaven's newest building, and its half-mile ring building received the internationally recognized certification in recognition of its "green" design and energy efficiency.
"Green" building design aims to use natural resources without waste, protect occupant health and improve employee productivity, and reduce pollution and environmental degradation. The LEED program, which stands for Leadership in Energy and Environmental Design, provides building owners and operators with a framework for identifying and implementing practical and measurable green building design, construction, operations and maintenance solutions.
A team of architects, engineers, construction managers and contractors worked to implement sustainable design for the NSLS-II. The facility was designed by HDR Architecture, Inc., of Alexandria, Virginia. HDR staff trained in LEED requirements helped to come up with ideas to incorporate sustainable design and to manage the LEED application and certification process.
The architects built in sustainable design from the start and the contractors and construction crews contributed by recycling waste and using sustainable materials and work practices to help get the maximum points to achieve the Gold certification.
The NSLS-II ring building is Brookhaven's third facility to be awarded LEED certification. Additional buildings within the NSLS-II facility, as well as the nearly completed Interdisciplinary Science Building, are also expected to achieve recognition under the LEED program.
Suresh Srivastava, a longtime researcher at Brookhaven, was recently selected as the new president-elect of the World Association of Radiopharmaceutical Molecular Therapy, or WARMTH.
WARMTH is an international organization with 400 members that include nuclear medicine physicians, radiochemists, physicists, and oncologists from more than 50 countries. Its members work to advance science and education relating to therapeutic nuclear medicine and radiopharmaceutical therapy for the benefit of public health around the world.
At Brookhaven, Srivastava, a pioneer in developing personalized medicine – customized, low-dose methods to fight cancer and other life-threatening diseases, heads the Medical Isotope Research and Production Program. He and his collaborators use the Brookhaven Linac Isotope Producer (BLIP) to create radioisotopes not available commercially for the nuclear medicine community and industry for treatments and research.
