LHC injector chain

Target entity: LHC injector chain
Context triple: [Linac4, partOf, LHC injector chain]

• A. 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.
• B. Compact Linear Collider test facilities
  The Compact Linear Collider test facilities are experimental research installations at CERN dedicated to developing and validating technologies for a future high-energy electron–positron linear collider.
• C. 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.
• D. 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.
• E. 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.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: LHC injector chain
Target entity description: The LHC injector chain is the sequence of accelerators and beamlines at CERN that progressively boost and prepare particle beams before they are injected into the Large Hadron Collider.
