    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.

    • Adam Stavola – Deputy Radiation Control Manager

      Health physicist chairs inaugural DOE-wide artificial intelligence learning committee

      Deputy Radiation Control Department Manager Adam Stavola knows how to learn. The health physicist at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility has spent all but eight years of his life in a formal academic program. So, when the U.S. Department of Energy was putting together an inter-lab task force to study and implement new artificial intelligence (AI) technologies, Stavola eagerly volunteered to be involved.

      “I’m pursuing a Ph.D. in AI, so this new taskforce was very interesting to me,” he said.

      The group formed in December 2022 and named Stavola as its chair.

      “AI has advanced so much that leaders within the DOE determined that we need to learn about ways we can use AI in labs across the country,” Stavola explained. “The goal is for all the different laboratories within the DOE to pool together and try to solve specific problems using AI to help.”

      Learning on the job

      For the first project, the AI taskforce is focused on improving operational processes—due largely to the relatively low risk of applying AI in these situations.

      “By choosing to incorporate AI with an operations project, our learning doesn’t have a direct safety impact,” Stavola said. “We’ve picked something for our first project that has a low potential for causing problems. If it works, great. If it doesn’t, we haven’t hurt anything.”

      Stavola also notes that this project has the further benefit of opening lines of communication between loosely connected operations counterparts in labs across the country.

      “Researchers across labs work together a lot, but operations teams don’t necessarily collaborate among the labs,” said Stavola. “We want to see how we can use AI to make operations more efficient by using data from all labs. Maybe AI can help us improve on best practices. Maybe it will enable us to make better predictions.”

      Stavola also recognizes that AI may have a significant impact on efficiently processing data gleaned from laboratory operations.

      “We are also trying to use AI to take care of things that would take humans too long,” he continued. “One of the things we do is look at our lessons learned. AI will mine the incredible amount of data we have about what has happened in the past in order to make predictions. So, if we are experiencing something, AI can notify us if we’ve previously been in a similar situation, and it can tell us what to expect.”

      Stavola notes that AI is not being developed to work completely autonomously and without feedback from the human team.

      “An example of how we might use AI, but not trust it fully, is: if AI detects potential for rain, we might grab an umbrella before we leave the house,” he explained. “Of course, we still check for rain when we step outside and before we open the umbrella.”

      AI as more than a task force project

      While Stavola is enthusiastic about his work with AI, he admits that his role on the AI task force represents only a small percentage of his responsibilities at the lab.

      “My main job—and really what takes up most of my day and what I’ve been doing since 2006—is that I’m a board-certified health physicist,” Stavola shares. “As a health physicist for the lab, my work is all about radiation protection for laboratory staff, the environment and the general public.”

      Stavola has a master’s degree in electrical and electronics engineering from Old Dominion University (ODU) and a master’s degree from Christopher Newport University in applied physics and computer science. Currently, he is a Ph.D. candidate at ODU researching how AI can use meteorological data to predict relative uranium concentrations in soil.

      Like the AI learning taking place at the lab, Stavola says he is invested in his own unending process of intentional learning, which he views as his biggest hobby.

      “You get interested in all these things and you go down all these different pathways,” he laughed. “Some would say I’ve been a glutton for punishment; I’ve been in school my entire adult life. I’m constantly trying to get better at what I’m doing. It’s about pushing myself. And, yes, learning is my biggest hobby. Otherwise, this much school doesn’t make any sense!”

      “I’ve learned that the more you learn, the more you realize you don’t know,” he said, recognizing that it’s a bit cliché. “The more you learn, the more you want to learn. I am constantly discovering things that I don’t know about, but I want to know about. And you learn about more niche subjects and say, ‘Oh this is new. Lemme go dig into this for a little while.’ You always want to push it a little more. I think most people are like that.”
