particle accelerator
 
 
A machine (sometimes called an “atom smasher”), often very large, that brings elementary particles (usually either protons or electrons) to a very high speed and then allows them to collide with a target. From the resulting behavior of the particles and the target, scientists deduce the structure of the particles.  1
‡ Almost all of our knowledge of the nucleus and of elementary particles depends on experiments using particle accelerators.  2
