The Linac 4 linear accelerator is earmarked to take over from the 30-year-old Linac 2 at the physics complex. It is 86m long and promises to deliver beams at 160MeV, compared with the 50MeV beams provided by its predecessor. Cern expects Linac 4 to come into operation in 2013, when it will act as the first link in the proton acceleration chain for the LHC.
The photo shows the movable tuner and RF power coupler in Linac 4's medium-energy beam transport line. The cable in the foreground waits for the tuner's stepper motor.

This shot by Matthias Raabe shows the accelerator tunnel for Hera, the Hadron Electron Ring Accelerator, at Desy in Hamburg. The two-ring accelerator, which took six years to build before coming online in 1990, is the world's only electron-proton collider. The Hera tunnel runs for 6km at a depth of up to 25m.
