Antiproton Decelerator

Target entity: Antiproton Decelerator
Context triple: [CERN, operates, Antiproton Decelerator]

• A. 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.
• B. Large Hadron Collider
  The Large Hadron Collider is the world’s largest and most powerful particle accelerator, used to smash subatomic particles together at unprecedented energies to study fundamental physics, including the Higgs boson.
• C. Super Proton Synchrotron
  The Super Proton Synchrotron is a high-energy circular particle accelerator at CERN that serves both as a research machine and as a key injector for the Large Hadron Collider.
• D. Linac4
  Linac4 is a linear accelerator at CERN that serves as the first stage of the proton acceleration chain for the Large Hadron Collider and other experiments.
• E. NA62
  NA62 is a high-energy physics experiment at CERN designed primarily to study rare kaon decays and test the predictions of the Standard Model.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
