World's first crabbing of a proton beam

CERN has successfully tested "crab cavities" to rotate a beam of protons – a world first. The test took place on 23 May using a beam from CERN's Super Proton Synchrotron (SPS) accelerator and showed that bunches of protons ...

Beams are back in the LHC

The Large Hadron Collider is back in business! On Friday 30 March, at 12:17 pm, protons circulated in the 27-km ring for the first time in 2018. The world's most powerful particle accelerator thus entered its seventh year ...

Collimators—the LHC's bodyguards

The performance of the LHC relies on accelerating and colliding beams made of tiny particles with unprecedented intensities. If even a small fraction of the circulating particles deviates from the precisely set trajectory, ...

Colliding protons head-on

They won't pinch you and you won't find them on the beach. The name of the new radio-frequency crab cavities has nothing to do with their appearance and is merely illustrative of the effect they will have on circulating proton ...
