Charged particle beam

A charged particle beam is a group of electrically charged particles that have approximately the same kinetic energy and move in approximately the same direction. Usually, the kinetic energies are much higher than the thermal energies of particles at ordinary temperatures.

The high energy and energy of the particles, typically expressed in (kilo/mega)electronVolt

• the intensity of the particle current, expressed in ampere

Both properties are often synthesized into the Electron beams, consisting of electrons.

• ion beams, consisting of ions.
