The large hadron collider

It is a giant circular tunnel built underground.

The vast machine, which occupies a 27km circular tunnel under the French-Swiss border, hunts for signs of new physics by slamming subatomic particles together at close to the speed of light.

The upgrade will make the collider far more sensitive to subtle quirks in the laws of physics, and physicists hope these anomalies will prise open the door to entirely new theories of the universe. If the upgrade goes to plan, the proton beams in the souped-up accelerator, known as the high-luminosity LHC, or HL-LHC, will be so intense that the number of collisions in the machine will be five to 10 times greater than today.

The standard model is a series of equations that describe how particles such as the electrons and quarks found inside atoms interact with each other.

The theory works brilliantly, but physicists know it is incomplete: The curious signals seen that the LHC in recent months are too tenuous to convince most physicists that they are real, but if they strengthen over time, as happened with the Higgs bosonthey could reveal the existence of completely unexpected new particles, dubbed leptoquarks or Z primes.

To ramp up the number of collisions at the LHC, engineers will fit powerful magnets to squeeze the protons into finer, more dense beams. This makes the protons rotate a smidgen the moment before they strike protons coming the other way, which drives up the number of collisions.

They are called crab cavities because they make the proton bunches move sideways, even if the rotation is minuscule. While new magnets and beam instruments will be installed when the LHC is switched off for two years inmost of the required equipment will be fitted in a longer shutdown from towhen the revamped machine will switch back on again.

It would be totally groundbreaking.After eight years of banging subatomic particles together, CERN's Large Hadron Collider (LHC) is getting a major upgrade.

In a ceremony on Friday, the high-energy physics laboratory broke ground. The Large Hadron Collider (LHC) is the world's biggest and most powerful particle was built by the European Organization for Nuclear Research ().It is a giant circular tunnel built underground. The tunnel is 17 miles (27 kilometers) long, and between 50 and meters below the ground.

It lies beneath the border of Switzerland and France. 10, scientists and engineers from. The Large Hadron Collider (LHC) is the world's largest and most powerful particle collider and the largest machine in the world. It was built by the European Organization for Nuclear Research (CERN) between and in collaboration with over 10, scientists and hundreds of universities and laboratories, as well as more than countries.

It lies in a tunnel 27 kilometres (17 mi) in.

The Large Hadron Collider (LHC) is the world's largest and most powerful particle collider, the most complex experimental facility ever built and the largest single machine in . But we might have had proof that they don't exist all along, because as British theoretical physicist Brian Cox recently pointed out, there's no room in the Standard Model of Physics for a substance or medium that can carry on our information after death, and yet go undetected in the Large Hadron Collider.

"If we want some sort of pattern that carries information about our living cells to.
