Target entity: M2 beam line Context triple: [North Area of CERN SPS, hasBeamLine, M2 beam line]
-
A.
M2 beam line
chosen
M2 beam line is a high-energy particle beam facility at CERN’s Super Proton Synchrotron used to deliver intense hadron and muon beams for fixed-target experiments such as COMPASS.
-
B.
T2 beam line
The T2 beam line is a particle beam transport line in CERN’s Super Proton Synchrotron (SPS) North Area used to deliver high-energy beams to experimental facilities.
-
C.
NuMI beamline
The NuMI beamline is a high-intensity neutrino production facility at Fermilab that generates neutrino beams for long-baseline particle physics experiments.
-
D.
CERN test beam lines
CERN test beam lines are specialized experimental facilities that deliver controlled particle beams to test and calibrate detectors and other high-energy physics instrumentation.
-
E.
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protons for injection into the Proton Synchrotron Booster and the rest of the accelerator complex before being superseded by Linac4.
- 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.
