-
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.
Antiproton Accumulator
The Antiproton Accumulator was a storage and cooling ring at CERN designed to collect, cool, and accumulate antiprotons for high-energy proton–antiproton collision experiments.
-
C.
Antihydrogen Laser Physics Apparatus
Antihydrogen Laser Physics Apparatus is a CERN-based experiment designed to produce, trap, and study antihydrogen atoms with lasers to test fundamental symmetries between matter and antimatter.
-
D.
proton–antiproton collider at CERN
The proton–antiproton collider at CERN was a high-energy particle accelerator complex that enabled the discovery of the W and Z bosons, confirming the electroweak theory of the Standard Model.
-
E.
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.
