Shrinking particle accelerators with cold plasma and a large picnic basket

Twenty-five feet below ground, SLAC National Accelerator Laboratory scientist Spencer Gessner opens a large metal picnic basket. This is not your typical picnic basket filled with cheese, bread and fruit--it contains screws, bolts, steel tubing, and many other parts and pieces that carry particles to nearly the speed of light. The components are arranged precisely to do an important job: help feed bunches of fast-moving electrons into the stuff that the sun is made of: plasma.
