A particle beam is a stream of charged or neutral particles, in many cases moving at near the speed of light.
There is a difference between creation and control of charged particle beams to neutral particle beams, as only the first type can be manipulated to a sufficient extent by devices based on electromagnetism. The manipulation and diagnostics of charged particle beams at high kinetic energies using particle accelerators are main topics of accelerator physics.

Famous quotes containing the words particle and/or beam:
“Each particle is a microcosm, and faithfully renders the likeness of the world.”
—Ralph Waldo Emerson (1803–1882)
“It was at that moment, just after Krug had fallen through the bottom of a confused dream and sat up on the straw with a gasp—and just before his reality, his remembered hideous misfortune could pounce upon him—it was then that I felt a pang of pity for Adam and slid towards him along an inclined beam of pale light—causing instantaneous madness, but at least saving him from the senseless agony of his logical fate.”
—Vladimir Nabokov (1899–1977)
