The Fermilab Tevatron could accelerate protons (and anti-protons) to kinetic energies of 1000 GeV (1 TeV). By how much (in units of m/s) does the speed of a 1 TeV proton differ from the speed of light?
What is the momentum of a 1 TeV proton?
In addition, estimate the magnetic field of the magnets used in the Fermilab Tevatron accelerator to bend the protons in their nearly circular orbit. The Tevatron magnets are laid out in the form of a ring of radius 1 km.
