October 7, 2022
  • Speaker: Todd Satogata
  • Affiliation: JLab/ODU – Center for Advanced Studies of Accelerators
  • Title: Accelerator Physics and the US Electron-Ion Collider
  • Host: Adriana Banu
  • Abstract: The Electron-Ion Collider (EIC) is being designed for construction at Brookhaven
    National Laboratory (BNL), as a joint Department of Energy effort between Jefferson Lab
    (JLab) and BNL. This accelerator will enable unprecedented precision measurements of nuclear systems, leading to an understanding of how the properties of nuclear matter (including
    mass) originate from QCD, the theory of the nuclear strong force. Technical design efforts
    are underway to focus on readiness for the next stage of federal approvals in late 2023. The
    speaker will present a current overview of the EIC design, with an emphasis on accelerator
    physics and technology challenges of this challenging new collider.

  • Title: Towards Detection of Ultrahigh Energy Neutrinos with the Radar Echo Telescope
  • Host: Giovanna Scarel
  • Abstract: Detection of ultrahigh energy (UHE) neutrinos is key to identifying the most
    energetic objects and processes in the universe. These are the sources of UHE cosmic rays
    which have been detected at earth with energies exceeding 1 Joule per nucleon (roughly the
    kinetic energy of a bird in flight). As UHE cosmic messengers, neutrinos are unparalleled
    for their ability to travel from source to Earth, interacting only weakly with matter and
    therefore able to traverse great distances unimpeded. For this same reason, however, they
    are very difficult to detect (further complicated by their very low flux at high energies). In
    this talk, I will discuss the challenges in detecting UHE neutrinos, the extensive experimental
    work that has been done so far to meet these challenges, and a forthcoming experimental
    effort, the Radar Echo Telescope, which uses well-known radar technology to detect the
    cascade produced by these elusive neutrinos as they interact in polar ice. I’ll discuss the
    theory and storied history of the radar echo method, recent laboratory work, and our current
    experimental efforts in service of UHE neutrino detection with radar.
