How to obtain particles to accelerate
Where do the particles come from that are accelerated in a particle accelerator? In this portion of a particle physics tutorial, three sources of particles are described for students. The first source is electrons, which come from heated metals. The second is protons, which are available from ionized hydrogen. Antiparticles are the third source. They are collected by magnetic fields after particles smash targets. Copyright 2005 Eisenhower National Clearinghouse
