CERN, Higgs Boson Fame, Now Ready for Second 3-Year Run

CERN, the premier institute known for its research on Higgs Boson or God Particle, and anti-matter will re-open its Large Hadron Collider (LHC) after shut-down since January 2013 for refurbishment as it has to go for its second three-year run.

CERN’s LHC is the largest and most powerful particle accelerator in the world and the institute said the whole 27-km superconducting machine is now almost cooled to its original and nominal operating temperature of 1.9 degrees above absolute zero.

All teams are at work to get the LHC back online and the CERN Control Centre is in full swing to carry out all the requested tests before circulating proton beams again in March 2015. The 2-year technical stop makes the machine ready for running at almost double the energy of the LHC’s first run, the institute said.

“With this new energy level, the LHC will open new horizons for physics and for future discoveries,” says CERN Director-General Rolf Heuer. “I’m looking forward to seeing what nature has in store for us”.

CERN said for the first time on 9 December 2014, the magnets of one sector of the LHC, one eighth of the ring, were successfully powered to the level needed for beams to reach 6.5 TeV, the operating energy for run 2.

The goal is to run with two proton beams in order to produce 13 TeV collisions, an energy never achieved by any accelerator in the past. The CERN is planning to achieve this milestone sometime in March 2015.

“After the huge amount of work done over the last two years, the LHC is almost like a new machine,” said CERN’s Director for Accelerators and Technology Frédérick Bordry. “Restarting this extraordinary accelerator is far from routine. Nevertheless, I’m confident that we will be on schedule to provide collisions to the LHC experiments by May 2015”.

Apart from the LHC, its four large experiments — ALICE, ATLAS, CMS and LHCb — are also undergoing major preparatory work for run 2, after the long shutdown for maintenance and upgrades. They will now enter their final commissioning phase, said CERN.
