U.S. Joins World in New Era of Research

Recently, scientists at the Large Hadron Collider at CERN started recording data from the highest-energy particle collisions ever achieved on Earth. This new proton collision data, the first recorded since 2012, will enable an international collaboration of researchers that includes more than 1,700 U.S. physicists to study the Higgs boson, search for dark matter, and develop a more complete understanding of the laws of nature.

 "Together with collaborators from around the world, scientists from roughly 100 U.S. universities and laboratories are exploring a previously unreachable realm of nature," said James Siegrist, U.S. Department of Energy's Associate Director, Office of High Energy Physics. "We are very excited to be part of the international community that is pushing the boundaries of our knowledge of the universe."

The Large Hadron Collider (LHC), the world's largest and most powerful particle accelerator, reproduces conditions similar to those that existed immediately after the Big Bang. In 2012, during the LHC's first run, scientists discovered the Higgs boson—a fundamental particle that helps explain why certain elementary particles have mass. 

Scientists will use this new LHC data to pin down properties of the Higgs boson and search for new physics and phenomena such as dark matter particles—an invisible form of matter that makes up 25 percent of the entire mass and energy of the universe. Physicists will also endeavor to answer questions like: Why is there more matter than antimatter? Why is the Higgs boson so light? Are there additional types of Higgs particles? What did matter look like immediately after the Big Bang?

In addition to serving as the U.S. host laboratory for the ATLAS experiment at the LHC, Brookhaven National Laboratory plays multiple roles in this international collaboration, from construction and project management to data storage, distribution, and analysis.

Brookhaven Receives Positive Results from Annual Audit

Brookhaven’s commitment to Integrated Safety Management includes Environmental, Safety and Health Management Systems structured on the International Organization for Standardization’s ISO 14001 and OHSAS 18001 Occupation Health and Safety Management standards. These rigorous standards provide a framework for the Lab to continually improve environmental, safety, and health performance. Each requires an annual audit by an independent third party to maintain certification. 

Recently, Brookhaven’s third party auditor, NSF International, a leading not-for-profit public health and safety organization, conducted the annual audit of how work is planned and executed as well as how the Lab monitors its own performance. The results were positive with the NSF International team issuing no non-conformances and citing two opportunities to improve our programs. The team also noted many positive aspects of our performance that included our improving accident rates and deer management efforts.

Summer Sundays – Your Opportunity to Visit BNL

summer sundays

Brookhaven National Laboratory has been opening its doors to the public for more than 50 years. This year, our “Summer Sundays” open houses will feature several of our world-class research facilities – the Center for Functional Nanomaterials, our new National Synchrotron Light Source, and the Relativistic Heavy Ion Collider – as well as the Science Learning Center and our Fire House where we’ll feature our safety and security operations. 

On July 12, visit the Center for Functional Nanomaterials, where Brookhaven researchers probe structures as tiny as a billionth of a meter. Learn about scientists’ latest discoveries in innovative energy technologies. Be amazed by the “Atoms, Molecules, Matter and More!” show in the Berkner Hall auditorium.

On July 19, tour the NSLS-II, the world’s brightest synchrotron light source! Learn how scientists will illuminate the inner workings of batteries and seek answers to some of the nation’s toughest energy challenges. Be enlightened by the “Science Laser Light Spectacular.” 

Family Fun Day will be held on July 26 at our Science Learning Center. A fabulous day of hands-on family fun! Use the basic scientific method to explore magnets, mirrors, and more! Hop aboard a fire truck at the Fire House and learn about the Lab’s protective services. Be mystified by the “Mystery & History of Magic.” 

Have “Atom-Smashing Fun” on August 2. Visit the Relativistic Heavy Ion Collider (RHIC), a world-class particle accelerator where physicists recreate the conditions of the universe as they believe it existed microseconds after the Big Bang! Stump a physicist and meet “Einstein” Alive.

Free fun, no reservations required! It’s always best to arrive early. Our gates open at 10 a.m. Science shows take place three times each Sunday in the Berkner Hall auditorium – Noon, 1:30 p.m., and 3 p.m. Just remember, visitors 16 and older must bring a photo ID.
