A look at the damage that halted the LHC
News This picture shows damage to the support of one of the quadrupole magnets in sectors three to four. The LHC uses quadrupole magnets to focus opposing proton beams, and dipole magnets to keep the beams on their respective paths.

LHC restart date now June at earliest
News The particle beams are held on their paths by dipole magnets and focused by quadrupole magnets. The world's most powerful particle accelerator will go live again in June at the earliest, following the fault that shut it down in September.

Cern: Electrical fault caused LHC helium leak
News Around a vacuum chamber, dipole magnets are used to keep two opposing proton beams on their paths, while quadrupole magnets focus the beams. Cern has confirmed that an electrical fault was the cause of a liquid helium leak in its flagship particle...

Progress made in Large Hadron Collider repair
News The magnet that was lowered underground on Thursday was a quadrupole: one of the magnets that focuses the particle stream, rather than one of the dipole magnets that keep the stream on course. The final replacement magnet for the Large Hadron...
