BRAINCAKEParticle Accelerators
A TV tube is an example of a particle accelerator. In a the TV tube, the electrons are accelerated through a potential difference of about 5000V.
The electron beam hits the inside of a screen
Magnetic fields formed by electromagnets deflect the beam so that it scans the screen to create an image.

Key terms in this lesson
- Antiparticle
- A particle with the same rest mass as its corresponding particle but with opposite charge and opposite values of other quantum properties.
- Hadron
- A particle made up of quarks that interacts through the strong interaction; hadrons are divided into baryons and mesons.
- Potential difference
- The energy transferred per unit charge as charge moves between two points in a circuit.
