    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

    "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.

    • Tim Minga, Fire Marshal

      As a child, Minga learned how to care for the special things in life. Now, as the first Jefferson Lab Fire Marshal, he cares for myriad buildings and staff. 

      When Timothy Minga was a little boy, growing up the middle child in a family of three sons in rural Smithfield, he would sometimes leave his bicycle in the front yard. But his grandfather, an oysterman who lived across the street, wanted to impress upon his grandchildren the importance of taking care of what you have; taking care of what is special.

      “If he thought for one minute that my bicycle was going to stay in the front yard and not be put in the garage, he would call the house,” Minga said.

      “I know you’re not going to leave that bicycle in the front yard,” Minga said, reenacting his grandfather’s teaching words.

      “‘No sir, no sir,’ and I’d run outside and put the bicycle back in the garage,” Minga said. But the lesson, Minga recalls, has stuck with him for life.

      “It wasn’t about him thinking someone was going to steal it,” Minga explained. “He didn’t want it to stay out in the dew and rust. He wanted you to take care of everything that you had.”

      Minga who has been appointed Jefferson Lab's first Fire Marshal, has built a career taking care of what is special. 

      “I have always been passionate about life safety,” Minga said.

      When he was 18 years old, Minga joined the Smithfield Volunteer Fire Department.

      As a teenager, Minga was one of the working firemen to run into the burning Smithfield Packing Co.’s smokehouse when it went ablaze.

      “I’ll never forget that,” Minga said. “It was an eerie condition to have to go into. You couldn’t see anything, and being a young firefighter, I was scared to death.”

      Minga’s desire to save lives pushed him onward. From running into burning buildings to rising through the ranks and dedicating his career to preventing fires, Minga faces challenges with determination.

      Seeing Minga’s potential during his time as a volunteer firefighter, his chief sent him to the University of Georgia at the age of 20 to further his studies on fire investigation, detection and suppression.

      “That’s when everything took off,” Minga said.

      Minga worked his way through the ranks, landing himself a position in the Newport News Fire Marshal’s office, where he worked as a Fire Inspector, Assistant Fire Marshal, Criminal Investigator and Deputy Fire Marshal.

      “The packaging plant fire taught me how quickly things can get out of control,” Minga said. “And throughout my career, it has always been about saving people’s lives. That is the primary goal.”

      It was with this mentality that Minga began working on the Jefferson Lab Experimental Hall D project as a Fire Marshal representing the City of Newport News. With his retirement date approaching, Minga applied to continue his work with Jefferson Lab, and eight years ago, he joined the team working on the Fire Protection Program. He was recently promoted to Fire Marshal, where he leads a Suppression Technician and Detection Technician to ensure all systems are tested, maintained and properly working.

      As a team of three, their responsibilities include testing and maintaining fire alarm systems and sprinkler systems, as well as completing assessments that ensure compliance with the Department of Energy’s requirements.

      Being adaptable and ready for anything is part of the job requirements. Working with an active laboratory, where experiments are constantly changing, requires the fire suppression and detection systems to change.

      “When they design an experiment, they’re in our halls,” Minga said. “It may run for two years and they rip the whole thing out and put a new experiment in, and the fire detection and suppression systems have to be re-designed around that experiment.”

      Minga has to assess whatever new potential dangers may be involved with that experiment and design a system prepared for any unplanned circumstances. Balancing the experimental side with the daily care and maintenance of the entire facility, Minga and his team never rest at work.

      When he isn’t working, Minga enjoys spending time with his family. A father to three children, one son and two daughters, and a partner to his wife, Minga enjoys spending time on the water.

      “I have had a boat and lived on the water all of my life,” Minga said.

      A family man who built his career on the foundation of saving lives, Minga hopes to be remembered as a hardworking man who loved his family on and off the water.

      “I couldn’t imagine being anywhere else.”
