Compositeness

The unprecedented energy of proton collisions at the LHC could be what scientists need to find a possible substructure for subatomic particles The Standard Model of particle physics tells us what elementary particles make up matter in the universe. As far as we know, the particles in the Standard Model are the basic building blocks of matter […]

ATLAS

“From a cavern 100 metres below a small Swiss village, the 7000-tonne ATLAS detector is probing for fundamental particles“ ATLAS is one of two general-purpose detectors at the Large Hadron Collider (LHC). It investigates a wide range of physics, from the search for the Higgs boson to extra dimensions and particles that could make up dark matter. Although it has the same scientific […]

Accelerating: Radiofrequency Cavities

To accelerate particles, the accelerators are fitted with metallic chambers containing an electromagnetic field known as radiofrequency (RF) cavities. Charged particles injected into this field receive an electrical impulse that accelerates them. In the Large Hadron Collider (LHC), 16 RF cavities are housed in four cylindrical refrigerators called cryomodules, which enable them to work in a […]
