electron beam

Particle stream, focused

An electron beam is a stream of electrons moving in the same direction, typically focused and accelerated through a vacuum.

Electron beams are used in cathode-ray tubes (the technology behind old televisions and computer monitors), electron microscopes, welding equipment, and particle accelerators.

The beam can be steered and focused using magnetic or electric fields.
