Large Hadron Collider Restarts Next Week but Won't Smash Any Particles Yet

The second run of the Large Hadron Collider will begin next week with new experiments. The beams, however, won't go full circle until March 25, according to scientists at CERN (European Organization for Nuclear Research) in Geneva.

The LHC was shut down in 2013 for power upgrades and equipment improvements that will allow it to generate more power to smash particles together as it searches for the elusive dark believed to make-up most of the mass of the universe.

Scientists have announced the machine is now ready to run at its "design energy," which only means it's ready for proton smashing experiments but with double the power of the first run.

Restarting the LHC, however, will be a gradual process since every step is as crucial as the next and should be taken carefully. Scientists working on experiments have decided to ensure that all the checking must be carried out and to not expect any proton beams until at least March 25.

They said this is on schedule since the restart of the LHC was previously promised during the week of March 23.

When the beams can accomplish laps across the LHC's pipes, the teams still don't expect any particle collisions for the next two months as this is a powerful process that should take its time.

According to CERN director general Rolf Heuer, the LHC is practically a new machine. That maintenance involved an inspection of every single one of the connections in the LHC's 10,000 magnets that guide the proton beams into a perfect circle.

The magnets should become steady as a rock even if they turn from cold to warm or vice versa, he said. These magnets are superconducting electromagnets frozen to -273 degrees Celsius to perform. The inside of the beams, however, can become really hot.

Heuer said they advise a very careful switching on to a high power laser since the energy from one beam alone energy can melt 500 kilograms of copper. When combined together, the beams can melt one ton of copper and nobody wants that to happen, he warns.
