Is a machine that uses electromagnetic fields to propel charged particles to very high speeds and energies, and to contain them in effectively-defined beams. Particle displacement or displacement amplitude is a measurement of distance of the motion of a sound particle from its equilibrium place in a medium as it transmits a sound wave. The SI unit of particle displacement is the metre (m). Generally it is a longitudinal wave of stress (reminiscent of sound), however it may also be a transverse w...
