## How fast does the LHC accelerate particles?

The LHC accelerates beams of particles, usually protons, around and around a 17-mile ring until they reach 99.9999991 percent the speed of light.

What particles does the LHC accelerate?

The Large Hadron Collider is the most powerful accelerator in the world. It boosts particles, such as protons, which form all the matter we know. Accelerated to a speed close to that of light, they collide with other protons. These collisions produce massive particles, such as the Higgs boson or the top quark.

### What would happen if you got hit by the LHC?

It would burn a hole through you—and then some. The scientists at the LHC would like to make two things very clear. First, it’s just a horrible idea to put any part of your body in front of the collider’s two proton beams. Were the beam spitting out single protons, there would be little chance of impact.

How much energy does a particle accelerator make?

It is a collider accelerator, which can accelerate two beams of protons to an energy of 6.5 TeV and cause them to collide head-on, creating center-of-mass energies of 13 TeV.

#### How much energy does the LHC use?

The total power consumption of the LHC (and experiments) is equivalent to 600 GWh per year, with a maximum of 650 GWh in 2012 when the LHC was running at 4 TeV. For Run 2, the estimated power consumption is 750 GWh per year.

How do we accelerate particles?

Accelerators speed up charged particles by creating large electric fields which attract or repel the particles. This field is then moved down the accelerator, “pushing” the particles along. In a linear accelerator the field is due to traveling electromagnetic (E-M) waves.

## How much energy does the LHC produce?

During LHC operations, the CERN site draws roughly 200 MW of electrical power from the French electrical grid, which, for comparison, is about one-third the energy consumption of the city of Geneva; the LHC accelerator and detectors draw about 120 MW thereof. Each day of its operation generates 140 terabytes of data.

### What is the largest particle accelerator in the world?

The Large Hadron Collider (LHC) is the most powerful particle accelerator ever built. The accelerator sits in a tunnel 100 metres underground at CERN, the European Organization for Nuclear Research, on the Franco-Swiss border near Geneva, Switzerland.
