Nuclotron

Target entity: Nuclotron
Context triple: [Joint Institute for Nuclear Research, hasResearchFacility, Nuclotron]

• A. Antiproton Accumulator
  The Antiproton Accumulator was a storage and cooling ring at CERN designed to collect, cool, and accumulate antiprotons for high-energy proton–antiproton collision experiments.
• B. Proton Synchrotron Booster
  The Proton Synchrotron Booster is a circular particle accelerator at CERN that increases the energy of protons from the linear accelerator before injecting them into larger synchrotrons in the accelerator complex.
• C. 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.
• D. Antiproton Decelerator
  The Antiproton Decelerator is a specialized CERN facility that slows down antiprotons to low energies for precision experiments in antimatter physics.
• E. Proton Synchrotron
  The Proton Synchrotron is a historic circular particle accelerator at CERN that has played a key role in high-energy physics research and in feeding beams to larger colliders.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
