-
A.
drift tube linac (DTL)
chosen
A drift tube linac (DTL) is a type of linear particle accelerator that uses a series of electrically driven drift tubes to progressively increase the energy of charged particle beams.
-
B.
Linac1
Linac1 is an earlier linear accelerator facility that served as the predecessor to Linac2 in a particle physics laboratory.
-
C.
Brookhaven Linac Isotope Producer
The Brookhaven Linac Isotope Producer is a particle-accelerator-based facility at Brookhaven National Laboratory that generates medical and research isotopes for nuclear medicine and scientific applications.
-
D.
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.
-
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protons for injection into the Proton Synchrotron Booster and the rest of the accelerator complex before being superseded by Linac4.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.
