  • LET'S BE CLEAR

    When writing, clarity is essential. If writing is unclear, the reader may become confused or frustrated, which may lead them to stop reading altogether. Using ambiguous words, or words that have more than one meaning, without clarification can make writing unclear. Pronouns like “their” or “it” are commonly ambiguous, as the following illustrates: “The project managers report potential risks and suggest approaches according to their guidelines.” What does “their” refer to? The project managers’ guidelines? The guidelines of the approaches? A simple rewording can clarify: “…managers report potential risks and, according to their guidelines, suggest approaches….” 

    Disconnected or oddly arranged wording also may cause a lack of clarity. In the following example, watch for the confusion over what took place and where: “The athlete said she and her team mutually agreed to part ways in an online video.” Does the video show the team agreeing to part ways or just the athlete announcing it happened? If the latter, then moving the “video posted” phrase would clarify: “In an online video, the athlete said….” 

    Looking carefully for ambiguities and removing them can sharpen your writing — and sharp writing keeps readers reading. For questions, contact Dave Bounds at x2859 (virtual office hours: Tuesday and Thursday, 9-11 a.m.). Happy writing!

  • WATCH YOUR TONE!

    All writing has a voice, which is often referred to as “tone.” Word choice and order, sentence and paragraph length and even punctuation are all factors that contribute to someone’s tone.

    A tone may be authoritative, conversational, scientific, diplomatic and so on. In these examples, note how all are saying essentially the same thing in varying tones:

    • The following documentation presents a full explanation of the incident as requested.
    • You’ll find everything that happened below.
    • To understand the incident, read on. All details are accounted for.

    There are several ways to write the same sentence and just as many ways to convey tone. Which of the above sounds like a professional statement? An informal comment? The answers reveal themselves in the details.

    When put together, words like “documentation” and “explanation” give an official tone. Personalized wording like “you’ll find” "read on” convey a confident, possibly casual tone. Wording matters! How does your wording make up your tone? What wording could you change to better suit your intended tone?

  • MAKE WRITING FLOW WITH “PARAGRAPHING”

    Just as the sentences in a good paragraph connect to create a train of thought, paragraphs themselves should flow together to create the train of thought for whatever it is you are writing. From introduction to body to conclusion, paragraphs are key. “Paragraphing” well is all about moving your reader’s attention smoothly from one paragraph to the next.

    Incorporating smooth transitions, or segues, between your paragraphs comes down to two methods. The first method is using key words in the start of the paragraph (or toward the beginning) that shape the reader’s expectations for what comes next. For example: Instead of “Several proposals came through...,” try starting your paragraph with “In the first proposal...” Delegating your discussion items into their own paragraphs not only directs your reader’s attention but organizes your own thoughts.

    The paragraph above did this by mentioning two transition methods but only discussing one. The second method is to feature key words in the concluding line of a paragraph to set up what comes next. A paragraph on IT updates might mention “...which brings up implications for cybersecurity,” in the concluding sentence. The next paragraph can then jump right into discussing those implications.

  • SENTENCES MATTER!

    Writing usually involves a lot of shaping and rearranging sentences. If one sentence is too long, awkwardly worded, or just “off,” it can distract readers. Assessing the way sentences are structured is essential to improving your writing skills.

    No matter the sentence, it always come down to the subject and the verb. For example: “She wrote.” Anything outside of this sentence just concerns the details. To expand on the example: “She wrote an assessment of the initial efforts of the new program, which began in FY 2021.” In that sentence, the subject remains “she” and the action remains “wrote.” The rest pertains to what she wrote about. To make this flow better, we could break the sentence in two: “She wrote an assessment of the program. The initial efforts began in FY 2021.”

    Which is easier to read? The longer sentence or the two shorter sentences? How would you restructure sentences in your own writing to allow for better flow and focus?

    Maintaining a subject/verb can ease the stress that comes with finding places to put the extra details. The subject/verb focus is key to creating compelling sentences.

  • Status

    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.
