Accelerating electrons#

A simple and common technique for accelerating electrons is shown in the figure, where there is a uniform electric field between two plates. Electrons are released from rest, usually from a hot filament, near the negative plate, and there is a small hole in the positive plate that allows the electrons to pass through it.
