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
