How are subatomic particles detected in the LHC?

Muhammad Al-Hakeem  asked the Naked Scientists:
In the LHC, where subatomic particles result, how can they be viewed?

Many thanks.

Muhammad Al-Hakeem.

What do you think?

There are 7 different detectors around the LHC. These include:

Particle detectors typically include the following methods:
  • Magnetic fields, which bend the path of charged particles, and provides clues to their charge, mass and energy
  • Geiger tube: A subatomic particle will cause a spark in gas
  • Transparent crystals which glow (scintillate) when a particle strikes them
  • Silicon chips that detect particles, like a digital camera
  • Metal plates that slow down particles
  • Lots of computer processing to capture the data and analyse it to determine what particles were produced, and with what energies. This also means lots of computer storage, and high speed data links to the experimental collaborators around the world
