-
A.
Antiproton Decelerator
chosen
The Antiproton Decelerator is a specialized CERN facility that slows down antiprotons to low energies for precision experiments in antimatter physics.
-
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.
Extra Low ENergy Antiproton ring
The Extra Low ENergy Antiproton (ELENA) ring is a deceleration and storage facility at CERN designed to slow antiprotons to very low energies for precision antimatter experiments.
-
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.
Continuous Electron Beam Accelerator Facility
The Continuous Electron Beam Accelerator Facility is a high-energy physics research installation that provides continuous beams of electrons for probing the structure of nuclear matter.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
Provenance (3 batches)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
