    Breakthrough Prize Honors Neutrino Research

    He missed the 'glitzy Oscars for science,' but that’s OK with Bob McKeown. McKeown is the Governor's Distinguished CEBAF Professor in William & Mary’s physics department as well as deputy director for science at Jefferson Lab. He was a participant in two of five experiments that share the 2016 Breakthrough Prize in Fundamental Physics.

    Amber Boehnlein Becomes Jefferson Lab’s Chief Information Officer; Takes Helm of IT Division

    Amber Boehnlein can’t remember a time when she didn’t love science.

    As a child, growing up in the small Ohio village of Germantown, Boehnlein (pronounced “Bane Line”) would often play math games with her grandmother. She taught herself how to code while in high school. When she went off to college, it was only natural that she chose to study physics.

    CERN Announces Discovery of Different Pentaquarks

    CERN, the European Organization for Nuclear Research, has announced that its LHCb experiment has discovered two possible pentaquark particles that haven't been seen before. If confirmed, these new particles will herald the discovery of a whole new class of particles.

    Pentaquarks gained international attention in 2003, when evidence for a lighter cousin of the pentaquarks announced by CERN was thought to have been found by experimenters at SPring-8 in Japan, the Department of Energy's Thomas Jefferson National Accelerator Facility, the Alikhanov Institute for Theoretical and Experimental Physics (ITEP) in the Russian Federation and the ELectron Stretcher and Accelerator (ELSA) in Germany.

    Scientists Mix Matter and Anti-Matter Results to Resolve Decade-Old Proton Puzzle

    Fans of science and science fiction have been warned that mixing matter with anti-matter can yield explosive results. And that’s just what physicists were counting on, in hopes of blowing wide open a puzzle that has confounded them for the last decade.

    The puzzle comes from experiments that aimed to determine how quarks, the building blocks of the proton, are arranged inside that particle. That information is locked inside a quantity that scientists refer to as the proton’s electric form factor. The electric form factor describes the spatial distribution of the quarks inside the proton by mapping the charge that the quarks carry.

    DOE Award Gives Grad. Student Opportunity to Help Make Major SRF Advancements

    For as long as Matthew Burton can remember, he has been into science. When asked how far back, he readily recalls trying to bend a laser with magnets for an elementary school science fair project.

    The young researcher has always been excited by technology, and physics, he says, gave him a path into that.

    After high school, he headed to James Madison University on a (science, technology, engineering and math) STEM scholarship to study fundamental physics, and then to The College of William and Mary for its Ph.D. physics program.

    Detector Group Leader Accepts Additional Role as Lab’s Chief Technology Officer

    Andrew “Drew” Weisenberger, head of the Experimental Nuclear Physics Division’s Radiation Detector and Imaging Group, recently accepted the additional role of Chief Technology Officer (CTO) for Jefferson Lab.

    As part of the detector group, Weisenberger has spent years advancing research to improve particle detector technology and seeking ways that discoveries in his field can be applied outside of the lab’s basic research program. He is part of the team that worked on the components and technology that brought to life a breast-cancer diagnostic device – a molecular-imaging camera – now commercially produced and sold by Dilon Technologies that can detect the tiniest of breast cancer tumors. Today that camera is used in hospitals and medical diagnostic centers around the world.

    New Shielding Is Designed to Put the Block on Neutrons

    Fifteen minutes seems like a lifetime to Paul Brindza. It's the average lifetime of a neutron, one of the many subatomic particles that scientists study at Jefferson Lab. While that may seem like a fleeting existence to us, the Hall C engineer says that it's more than enough time for the subatomic particles to do some real damage as they travel inside the hall.

    Now, Brindza and his colleague Bert Metzger have devised a system of products to stop neutrons and other particles before they can inflict harm on sensitive scientific equipment and computers. Their patented and patent-pending products are currently being installed in Hall C.

    Quarks Pair Up in Protons (and Neutrons)

    Ordinarily, physicists generally think of protons and neutrons as each containing three “valence” quarks, i.e. quarks that determine the charge of the proton or neutron. When they visualize the structure, they usually imagine these three quarks to be more-or-less on equal footing. Even so, puzzling data from an experiment carried out 40 years ago was thought to suggest that two of the quarks cluster together into what is called a diquark. However, there has been very little experimental evidence since then to support this idea - perhaps until now.

    Advisory Committee Recommends Continued Investment in Jefferson Lab

    A committee appointed by the U.S. Department of Energy and National Science Foundation to review and recommend the future course of nuclear physics research in the United States has issued a report supporting the continued funding of the experimental program at the U.S. Department of Energy's Jefferson Lab.

    When Melanie Goff, president of a small, minority, women-owned business, needed to find new business prospects in the federal government, she turned to Freda Hopper. Hopper has been working with small businesses looking to get their foot in the door to federal contracting as a small business program manager since 1998, serving small businesses from her position at Oak Ridge Operations Office in Oak Ridge, Tennessee.

    JLab Nanotube Research Leads To Newport News Start-Up (Daily Press)

    A 13,000 square-foot office suite in Oyster Point will likely be the first place in the world where boron nitride nanotubes — a high-tech product developed at Jefferson Lab — will be manufactured for commercial use, officials said. The nanotubes, first discovered in California in the 1990s, could be used in products as diverse as satellites, golf clubs and computer screens.

    JLab's role in FRIB at Michigan State University (The State

    Hendrik Schatz studies exploding stars — or more specifically, what connection exploding stars have to our planet’s existence and the existence of elements on Earth today.

    He suspects that about 15 billion years ago, stars either exploded or collided, sending radioactive particles into the universe. Eventually, these radioactive particles became stable, clinging together to form Earth and many of the elements we use today, such as gold and uranium.
