Target entity: Linac4 Context triple: [LHC Injectors Upgrade, appliesTo, Linac4]
-
A.
Linac4
chosen
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.
Linac2
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protons for injection into the Proton Synchrotron Booster and the rest of the accelerator complex before being superseded by Linac4.
-
C.
Linac1
Linac1 is an earlier linear accelerator facility that served as the predecessor to Linac2 in a particle physics laboratory.
-
D.
LINAC3
LINAC3 is a linear accelerator at CERN that provides heavy-ion beams as part of the injector chain feeding the Large Hadron Collider.
-
E.
LHC injector chain
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.
- 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.
