    More Than 12,000 Explore Jefferson Lab During Open House

    More than 12,000 people took advantage of the opportunity to attend Jefferson Lab’s “New Era of Science” Open House on April 30, 2016.

    The record-breaking turn out for a Jefferson Lab open house occurred despite cool temperatures and overcast skies. Assisted by more than 450 volunteers, visitors explored nearly all of the major facilities at the lab, including the CEBAF accelerator, three of the lab’s four experimental halls, the Low Energy Recirculator Facility, the Superconducting Radiofrequency Institute and the Data Center.

    Getting a better measure of spin with diamond

    Diamonds are one of the most coveted gemstones. But while some may want the perfect diamond for its sparkle, physicists covet the right diamonds to perfect their experiments. The gem is a key component in a novel system that enables precision measurements that could lead to the discovery of new physics in the sub-atomic realm — the domain of the particles and forces that build the nucleus of the atom.

    Explorations of this realm require unique probes with just the right characteristics, such as the electrons that are prepared for experiments inside the Continuous Electron Beam Accelerator Facility at Jefferson Lab.

    NMSU Undergrad Receives JSA Research Assistantship

    http://www.science.energy.govWaverly Gorman didn’t always want to study physics.

    She began her college career as a mechanical engineering major. Then she took a class on quantum mechanics, and she was hooked. Now, the 21-year-old New Mexico State University junior is the latest recipient of the Jefferson Science Associates (JSA) Minority/Female Undergraduate Research Assistantship (MFURA) at Jefferson Lab.

    Montgomery to Step Down as Jefferson Lab Director

    Hugh Montgomery, Director of the Thomas Jefferson National Accelerator Facility, announced today that he will resign his position after over seven years at the helm of the research facility.  He will also step down as the President and CEO of Jefferson Science Associates (JSA), a joint venture between the Southeastern Universities Research Association (SURA) and PAE. JSA is the management and operating contractor for the U.S. Department of Energy (DOE) facility.

    New Optical Fiber Network Being Installed at Lab to Expand Capacity

    Optical fiber networks carry the lifeblood of research facilities like Jefferson Lab. Bundles of these thin glass, fiber or plastic lines transmit vast amounts of information and data, coded into beams of light and traveling nearly as quickly.

    The lab’s original optical fiber network, installed in the late 1980s and early 1990s, was built to transmit data from CEBAF’s (then) three experimental halls and for high-speed Internet connectivity. Over the years, many of the lab’s infrastructure and utilities systems were also moved onto the fiber optic network; and it now carries operational data for everything from telecommunications and email to security and heating, ventilation and cooling.

    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.
