Large Hadron Collider set for a restart post short-circuit issue

By  | 

The Large Hadron Collider (LHC) is all set for a restart this month as engineers at the European Organization for Nuclear Research’s (CERN) have managed to resolve the March 21 short circuit.

CERN has revealed that teams are in the final stages of testing after solving the March 21 issue – the problem that delayed the restart of the accelerator. the research organization also revealed that they are expecting the first beams to arrive as early as Saturday if all goes well.

“We are confident of being able to restart the machine over the weekend, as all of the tests performed so far have been successful,” said Frédérick Bordry, Director for Accelerators and Technology at CERN.

When the LHC and the whole accelerator chain are running, operators work in shifts around the clock in the control room. They will attempt to circulate beams in the LHC in both directions, at their injection energy of 450 GeV, as soon as all the lights are green.

Particle collisions at an energy of 13 TeV could start as early as June.

The short circuit was triggered on March 21 and it was initially believed that the issue could take weeks to resolve, but the engineers at CERN got the issue resolved in just 10 days. CERN revealed that the short circuit has affected one of LHC’s powerful electromagnets thereby delaying preparations in sector 4-5 of the machine. We would like to remind our readers that this is the same sector wherein a more eventful false start was triggered when the particle collider first commenced operations in 2008.

“Any cryogenic machine is a time amplifier,” Bordry had said at the time. “So what would have taken hours in a warm machine could end up taking us weeks.”
