LHC Parameters

Taking a closer look at LHC

Many of the values and parameters below are explained in more detail in the section Physics at LHC.

Some of the more important parameters.

  • Particles used: Protons (in proton- proton collisions) and heavy ions (Lead 82+)
  • Circumference: 26659 m.
  • Injected beam energy: 450 GeV (protons)
  • Nominal beam energy in physics: 7 TeV (protons)
  • Magnetic field at 7 TeV: 8.33 Tesla
  • Operating temperature: 1.9 K
  • Number of magnets: ~9300
  • Number of main dipoles: 1232
  • Number of quadrupoles: 858
  • Number of correcting magnets: 6208
  • Number of RF cavities: 8 per beam; Field strength at top energy ≈ 5 MV/m
  • RF frequency: 400 MHz
  • Revolution frequency: 11.245 kHz.
  • Power consumption: ~180 MW
  • Gradient of the tunnel: 1.4%
  • Difference between highest and lowest points: 122 m.

The values presented here are essentially what the machine presents, but repairs, improvements and upgrades during long shutdown (LS) cause some of them to vary slightly.
