Highest energy particles in a particle accelerator
Who
Large Hadron Collider
Where
Switzerland (Geneva )
When
2008

The proton beams of the Large Hadron Collider are capable of being accelerated by magnets up to within around a millionth of a percent of the speed of light. This means each proton will have around 7 TeV of energy (7 tera electron volts), equivalent to the energy used by 7 flying mosquitoes. Combined, all the protons in the active beams have the energy equivalent to 900 cars travelling at 100 kph.
