Here’s one we made earlier…
Now we zoom in on this blood
White blood cells
Red blood cells
Proton
Neutron
We can combine two neutrons and two protons to make….

Quark Symbol Spin Charge Mass
Up U 1/2 +2/3 360 MeV
Down D 1/2 -1/3360 MeV
Charm C 1/2 +2/3 1500 MeV
Strange S 1/2 -1/3 540 MeV

Neutrinos pass straight through you, just like this!
What Is CERN?
• CERN sits astride the Franco–Swiss border, near Geneva.
• CERN primarily consists of Particle Accelerators, which speed up the particles and then crash them together in order to find out what they are made of.
Particle Accelerators
• Particle Accelerators speed particles up to close to the speed of light.
• There are two different types, Linear and Circular.• These particles are sped up using electric fields, and
curved round using a magnetic field.• The new particle accelerator that they are building will be
the biggest and most powerful in the world.
Particle Detectors
• Once the particles have been created they have to be detected.
• It is quite difficult to detect some particles, as you cannot see them using ordinary light.
The ATLAS detector At CERN
Used more iron in its construction than all the Iron in the Eiffel Tower
The final result of a Tracking Chamber even though it can’t ‘see’ the particles

• We are now going to produce a model of what goes on in a particle accelerator.
• Please do everything correctly, it will be fun!
