In a cyclotron, or toroidal particle collider, such as the LHC in Geneva, streams of protons are accelerated in oppoisite directions by magnetic fields and then are deflected to collide head-on. The resulting burst of sub-atomic particles tells us much about the nature of the universe. Digital, for Scientific American, 2005. © 2005 by Don Dixon.
