-
A.
LINAC3
LINAC3 is a linear accelerator at CERN that provides heavy-ion beams as part of the injector chain feeding the Large Hadron Collider.
-
B.
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.
-
C.
Linac2
chosen
Linac2 was CERN’s long-serving linear accelerator that pre-accelerated protons for injection into the Proton Synchrotron Booster and the rest of the accelerator complex before being superseded by Linac4.
-
D.
Accelerator Test Facility
The Accelerator Test Facility is a specialized research installation at Brookhaven National Laboratory dedicated to developing and testing advanced accelerator and beam physics technologies.
-
E.
Linac1
Linac1 is an earlier linear accelerator facility that served as the predecessor to Linac2 in a particle physics laboratory.
- 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.
