Context triple: [CLAS, fullName, CEBAF Large Acceptance Spectrometer]
  • A. SLAC Large Detector
    SLAC Large Detector was a particle physics detector at the Stanford Linear Accelerator Center used primarily for precision studies of Z boson decays in electron-positron collisions.
  • B. High Momentum Spectrometer
    The High Momentum Spectrometer is a precision magnetic spectrometer used in nuclear and particle physics experiments to accurately measure the momenta and trajectories of high-energy charged particles.
  • C. Brookhaven Linac Isotope Producer
    The Brookhaven Linac Isotope Producer is a particle-accelerator-based facility at Brookhaven National Laboratory that generates medical and research isotopes for nuclear medicine and scientific applications.
  • D. SPEAR storage ring
    The SPEAR storage ring is an electron storage ring at SLAC National Accelerator Laboratory that historically served as both a particle physics collider and a synchrotron radiation source, forming the basis for later upgrades like SPEAR3.
  • E. SPS Heavy Ion and Neutrino Experiment
    The SPS Heavy Ion and Neutrino Experiment (NA61/SHINE) is a fixed-target particle physics experiment at CERN’s Super Proton Synchrotron that studies hadron production in proton, pion, and ion collisions for strong-interaction physics and neutrino beam characterization.
