How does a magnetic field affect a charged particle
It makes it move in a circular path because a force is constantly acting in the same perpendicular direction

What is a cyclotron
A particle accelerator

How does a cyclotron work
Two D's are connected to an alternating current and a charged particle is attracted to either D whilst a magnetic force keeps it moving in a circle
4 of 12
Why do we use particle accelerators
To create radioactive isotopes for PET scanners and to find put how the universe was created
5 of 12
What is the Large Hadron collider
A particle accelerator that tries to recreate conditions similar to just after the big bang by colliding protons at very high speeds
6 of 12
What is an elastic collision
Where momentum and kinetic energy are conserved
7 of 12
What is an inelastic collison
Where only momentum is conserved ad some kinetic energy is lost to heat and sound
8 of 12
What is the equation for momentum
mass x velocity
9 of 12
What is annihilation
Where two anti matter collide and have a momentum of zero because they are the same mass and travelling at the same velocity then collide to produce two gamma rays with a momentum of 0
10 of 12
What is annihilation used in
Detecting tumors in PET scanners
11 of 12
What is triangulation
Where the pairs of gamma rays are detected by the computer in a PET scanner and the tumor is along that path
