Atlas LHC Experiment  Photo produced by CERN

Manufacturer: European Organization for Nuclear Research (CERN)

First Successful Proton Firing: Sept 10, 2008

Location: Near Geneva, Switzerland

Type: Worlds largest and highest energy particle accelerator

Cost: $4.4 billion projected

Circumference: 17 miles

Speed:  Protons are accelerated to slightly lower than the speed of light.

Design: Over 10,000 scientists and engineers collaborated to design and construct it.

Purpose: By having fast moving particles travel around the circumference of the collider, they are sped to nearly the speed of light and then collided.  The collision produces new particles among other things.  High energy physicists are able to test hypothesis from studying these results and better understand the nature of our universe.

Trivia: The term hadron refers to particles composed of quarks.
