    Status

    More information about the status of an electron-ion collider can be found in the documents linked below. In 2018, the National Academies of Sciences, Engineering and Medicine issued a report, “An Assessment of U.S.-Based Electron-Ion Collider Science.” Following the report, the directors of Thomas Jefferson National Accelerator Facility and Brookhaven National Laboratory issued a joint statement of support. More information about the impetus for building an electron-ion collider can be found in the 2015 Long-Range Plan, issued by the Nuclear Science Advisory Committee..

     

  • Benefits

    Benefits

    Beyond sparking scientific discoveries in a new frontier of fundamental physics, an Electron-Ion Collider will trigger technological breakthroughs that have broad-ranging impacts on human health and national challenges. Research on the technologies needed to make this machine a reality is already pushing the evolution of magnets and other particle accelerator components. 
     
    Some of these advances could lead to energy-efficient accelerators, thereby dramatically shrinking the size and operating costs of accelerators used across science and industry for example, to make and test computer chips; to deliver energetic particle beams to zap cancer cells; to study and design improved sustainable energy technologies such as solar cells, batteries, and catalysts; and to develop new kinds of drugs and other medical treatments. New methods of particle detection developed for an EIC could also lead to advances in medical imaging and national security. 
     
    In truth, it’s nearly impossible to predict what will come from the knowledge gained from an EIC. History shows that applications springing from a deeper understanding of matter and fundamental forces things like GPS, microelectronics, and radiological techniques for diagnosing and treating disease often emerge many years after the foundational physics discoveries that make them possible. 
     
    But one thing is certain: Building the experiments that inspire and train the next generation of scientific explorers is essential for maintaining U.S. leadership in nuclear science and for developing the high-tech workforce needed to address some of our nation’s deepest challenges.

    Design

    "Design"

    The Electron-Ion Collider would consist of two intersecting accelerators, one producing an intense beam of electrons, the other a beam of either protons or heavier atomic nuclei, which are then steered into head-on collisions.

    The accelerators will be designed so that both beams can be polarized to around 70 percent for electrons, protons and light nuclei. Electrons will be able to probe particles from protons to the heaviest stable nuclei at a very wide range of energies, starting from 20–100 billion electron-volts (GeV), upgradable to approximately 140 GeV, to produce images of the particles’ interiors at higher and higher resolution. At least one detector and possibly more would analyze thousands of particle collisions per second, amassing the data required to tease out the smallest effects required for significant discoveries.

    Building the EIC will require the same core expertise that led to the versatility of the polarized proton and heavy ion beams at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory, and the unique polarized electron beam properties of the Continuous Electron Beam Accelerator Facility (CEBAF) at Thomas Jefferson National Accelerator Facility. These two Department of Energy laboratories have been collaborating on initial studies and developing designs that make use of key existing infrastructure and capitalize on investments in science and technology. Each design approach would require the development of innovative accelerator and detector technologies to answer the questions described in this brochure.

     

  • Goals

    Goals

    There are many scientific questions that researchers expect an Electron-Ion Collider will allow them to answer. Among them are four main topics of study. 

     

    3D Structure of Protons and Nuclei
    3D Structure of Protons and Nuclei
    Scientists would use the Electron-Ion Collider to take three-dimensional precision snapshots of the internal structure of protons and atomic nuclei. As they pierce through the larger particles, the high-energy electrons will interact with the internal microcosm to reveal unprecedented details—zooming in beyond the simplistic structure of three valence quarks bound by a mysterious force. Recent experiments indicate that gluons—the glue-like carriers of the strong nuclear force that binds quarks together—multiply and appear to linger within particles accelerated close to the speed of light, and play a significant role in establishing key properties of protons and nuclear matter. By taking images at a range of energies, an EIC will reveal features of this “ocean” of gluons and the “sea” of quark-antiquark pairs that form when gluons split—allowing scientists to map out the particles’ distribution and movement within protons and nuclei, similar to the way medical imaging technologies construct 3D dynamic images of the brain. These studies may help reveal how the energy of the massless gluons is transformed through Einstein’s famous equation, E=mc2, to generate most of the mass of visible matter.
    Solving the Mystery of Proton Spin
    Solving the Mystery of Proton Spin
    The Electron-Ion Collider would be the world’s first polarized electron-proton collider where both the electron and proton beams have their spins aligned in a controllable way. This polarization makes it possible to make precision measurements of how a proton’s constituent quarks and gluons and their interactions contribute to the proton’s intrinsic angular momentum, or spin. Spin influences the proton’s optical, electrical, and magnetic characteristics and makes technologies such as MRI scanning work, but its origin has eluded physicists ever since experiments in the 1980s revealed that quarks can account for only about a third of the total spin. More recent experiments show that gluons make a significant contribution, perhaps even more than the quarks. An Electron-Ion Collider would produce definitive measurements of the gluons’ contributions, including how their movements within the proton microcosm affect its overall spin structure—thus providing the final pieces needed to solve this longstanding puzzle.
    Search for Saturation
    Search for Saturation
    Capturing the dynamic action of gluons within protons and nuclei will give scientists a way to test their understanding of these particles’ ephemeral properties. As gluons flit in and out of the vacuum, multiplying and recombining, scientists suspect they may reach a steady state of saturation called a “color glass condensate.” This unique form of nuclear matter gets its name from the “color” charges that mediate the interactions of the strong nuclear force, and the dense, glasslike walls these particles are thought to form in nuclei accelerated to nearly the speed of light, seemingly suspended by the effects of time dilation. Scientists will use the Electron-Ion Collider to search for definitive proof of whether this form of matter exists, and test the limits of gluons’ ability to expand beyond the bounds of a single proton/ neutron inside a nucleus. They’ll also explore the mechanism that keeps gluon growth in check, like a lid clamping down on an overflowing popcorn pot. Precisely measuring the strength of the gluon fields, which constitute the strongest fields found in nature, will tell us how gluons interact with each other and how they contribute to building the bulk of visible matter in the universe today.
    Quark and Gluon Confinement
    Quark and Gluon Confinement
    Experiments at an EIC would offer novel insight into why quarks or gluons can never be observed in isolation, but must transform into and remain confined within protons and nuclei. The EIC—with its unique combinations of high beam energies and intensities—would cast fresh light into quark and gluon confinement, a key puzzle in the Standard Model of physics.

      Jefferson Lab’s Scientific and Technical Information Manager Credits Career to Eclectic Experiences and Interests

      Kim Edwards, daughter of an USAF airman and Japanese mother, traveled often by car.

      “Every time we changed duty stations, we drove from Point A to Point B, even if Point B was an airport to take us across an ocean,” Edwards remembered.

      There was a something special about these coast-to-coast car travels, though. Her father, an admirer of natural science museums, would stop at every museum from Point A to Point B.

      “Every podunk, obscure museum, we’d stop,” Edwards said, laughing. “My dad would stand in front of an artifact and stare for long minutes.”

      Edwards developed an appreciation for science and the preservation of its ever-advancing pursuit of knowledge. Today, as Jefferson Lab’s Scientific and Technical Information (STI) Manager, she finds herself standing and staring at science, the same way her father did during all of those obscure museum visits.

      “That’s who I am today too, I guess,” Edwards said, laughing.

      Edwards’ journey to Jefferson Lab isn’t as simple as traveling from Point A to Point B. Instead, she said, “My background is as eclectic as my decorating style. As a whole, it put me on the path I'm on.”

      Born at a U.S. Air Force Base in Japan, Edwards has lived in 10 cities, and she moved to the United States when she was four. As a young child, she dreamed of playing the flute professionally and studying under the world-renowned musicians of Juilliard. Her dedication and work ethic kept up with her passion, as she played flute in the band at Aliamanu Middle School in Honolulu and performed in the All-State Band.

      After high school, Edwards joined the United States Army, where she began pursuing her college studies. Open to varying ideas for her future, Edwards started with studying English at the University of Maryland while she was stationed in Germany.

      “I thought I wanted to be an English teacher,” she said. But then the Army transferred her to Fort Riley, Kansas, and she thought she could study accounting at Kansas State University, a natural progression since her Army job was 73C - Finance Specialist. It was an elective class - Forensic Anthropology - that stole her intrigue and curiosity. She enjoyed learning about the anatomical science of anthropology.

      Her interests didn’t stop there. After she was honorably discharged from the army, she returned to Hampton Roads and finished a B.A. in Communication Arts with a minor in Business Administration from Christopher Newport University.

      “See?” Edwards said. “Eclectic. I think all of these experiences and interests helped me to be adaptable and flexible.”

      Being adaptable and flexible were exactly the qualities Jefferson Lab looked for in 2000 when they sought a Technical Information Specialist. Edwards applied for the job because, “I was tired of driving across the Hampton Roads Bridge Tunnel.”

      That job, however, opened the door for Edwards to exercise her interest in science, her respect for record keeping, her discipline from the army, and her appreciation for language arts. Her first task was to streamline the publications process.

      “So Publications Manager became my title,” Edwards said.

      Ten years later, she received her certification in records management from the Institute of Certified Records Managers.

      “So Certified Records Manager became my title,” Edwards said.

      No matter the title, Edwards brought to her work all of her varied passions, backgrounds and experiences. Today, as the STI and Records Manager, she manages the Jefferson Lab History Archives Program, as well as ensures the lab stays compliant in the way records and scientific/technical information are managed.

      For nearly two decades, Edwards has collected, reviewed, and protected scientific documents, artifacts, audio and video files. She has also played a critical role in developing processes for the archive program.

      “I’m excited that a hundred years from now, historians and researchers will be using the Jefferson Lab History Archives to make new discoveries of their own and to share them in academic papers,” Edwards said.

      Edwards is married to Kelvin Edwards, who leads the Systems Team in the Computing, Networking and Infrastructure department. They live with two cats and one recently adopted dog.

      “We got a discount on her because she’s an older dog and had been at the shelter for months,” Edwards said, laughing.

      If she’s not searching for funding for the archives program, or managing the submission of journal articles, or working on records accessions, she’s working on her Master’s degree at San Jose State University, updating her dog’s Facebook page or crocheting, a hobby she picked up from her grandmother in the 1970’s while they watched Hawaii Five-O or listened to Elvis records.

      Edwards looks back on her life and her work with appreciation.

      “When I’m 95 years old, I hope I will be one of those people who worked in the background to affect other people’s lives for the better,” Edwards said.

      “And I’d also like to be able to remember what I ate for dinner.”
