LHC

The Large Hadron Collider physics program has begun

After months of testing, the Large Hadron Collider research program has started at the European Organization for Nuclear Research (CERN) laboratory on the Franco–Swiss border. Accelerating particles and colliding them at 7 trillion electron volts - just half of its full capacity, but already three and a half times the energy previously achieved by the most powerful particle accelerator in the United States - scientists at LHC are now hoping to answer fundamental questions on the nature of our universe.  Read More

The successful restart of the Large Hadron Collider prompted scenes of jubilation

Contrary to claims by some scientists that the Large Hadron Collider (LHC) was being sabotaged from the future to save the world, it is back up and running. The LHC is now beyond the point where it was in 2008 when it had to be shut down just nine days after it had commenced sending beams around its 27km (17 mile) circuit on September 10 last year.  Read More

The LHC has undergone substantial repairs since its initial outing

The date 10 September 2008 was forseen by some as the end of the world, at least if you believed scientists who were trying to pull the plug on an experiment that some dubbed the ‘Doomsday Test’. As it turned out a faulty electrical connection brought proceedings to a halt. Now the $9 billion ‘atom-smasher’, aka the Large Hadron Collider, which was developed by CERN to recreate the chemical reactions that took place when the universe came into existence around 14 billion years ago, is gearing up for a restart.  Read More

LHC reaches temperatures colder than outer space

April 11, 2007 The first sector of CERN ’s Large Hadron Collider (LHC) to be cooled down has reached a temperature of 1.9 K (-271°C) - colder than deep outer space! Although just one-eighth of the LHC ring, this sector is the world’s largest superconducting installation. The entire 27-kilometre LHC ring needs to be cooled down to this temperature in order for the superconducting magnets that guide and focus the proton beams to remain in a superconductive state. Such a state allows the current to flow without resistance, creating a dense, powerful magnetic field in relatively small magnets. Guiding the two proton beams as they travel at nearly the speed of light, curving around the accelerator ring and focusing them at the collision points is no easy task. A total of 1650 main magnets need to be operated in a superconductive state, which presents a huge technical challenge.  Read More
