Paperclips dance upright on top of the world's largest cyclotron at Triumf, activated by a fringe magnetic field. High-school student Ali Lambert's photo won first place in the Canadian lab's local contest.

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.
