CERN’s Large Hadron Collider

What is CERN?

CERN is European Organization for Nuclear Research

CERN studies FUNDAMENTAL PARTICLES – the basic particles

What is the Large Hadron Collider?

The LARGE HADRON COLLIDER , or the LHC , is a machine built by CERN

Its point is to solve some questions about the universe

and to re-create the conditions after the BIG BANG

Then it will also be possible to see what will happen to the universe later

because it is approximately 27 km in circumference. Large Hadron Collider

Large Hadron Collider Hadrons are particles made only of QUARKS. *

because inside the machine, particles collide. Large Hadron Collider

* QUARKS and LEPTONS are FUNDAMENTAL PARTICLES

* Protons and neutrons are made up of QUARKS Electrons are types of LEPTONS

The first time it was lounged September 2008

During the first run, the magnets of the LHC cooled down, and the experiment couldn’t be carried out

It took over a year to fix the LHC

The next time it was lounged 20 Nov 2009

We do not know how long the experiment will last since no one has ever done it before

It might last for years

How does the LHC work?

STEP 1:

Electrons are taken away from hydrogen atoms, so that only protons are left

OR

By accelerating lead vapor, electrons are taken away from lead atoms, so that only the nucleus is left

STEP 2:

Beams of HADRONS in the LHC are shot in different directions

At certain points, beams collide, gaining more speed

The maximum speed that the hadrons can reach is 0.999999991 the speed of light

Nothing can go faster than light. However, there is no limit to energy

Scientists hope to gain so much energy that it will be enough to create a model of the

BIG BANG
