ATLAS is the largest detector that explores nature's fundamental particles and forces. This includes the search for Higgs particles, supersymmetric particles, extra dimensions, and the like. At the ATLAS detector center, particles collide at very high energies.

ALICE is a large detector dedicated to searches within heavy-ion physics. It is designed to study the physics of strongly interacting matter at extreme energy densities, where a phase of matter called quark-gluon plasma forms.

ISOLDE is the Isotope mass Separator On-Line facility. It is a unique source of low-energy beams of radioactive nuclides, those with too many or too few neutrons to be stable. In fact, the facility fulfils the old alchemical dream of changing one element into another. It permits studying the vast territory of atomic nuclei, including the most exotic species.

AEgIS has its main scientific goal to directly measure the earth's gravitational acceleration, g, on the anti-material antihydrogen. This is done by making a jet of antihydrogen and measuring how much the jet falls as it passes through an instrument called a Moire deflectometer.

CMS is a general-purpose detector with a broad physics programme ranging from studying the Standard Model to searching for extra dimensions and particles that could make up dark matter. Although somewhat similar to ATLAS it uses different technical solutions and a different magnet-system design.
