Electron multiplication is a process where a single electron triggers a cascade of secondary electrons, significantly amplifying the original signal. This phenomenon is crucial in devices like photomultiplier tubes and electron multipliers, which are used to detect and measure low levels of light and radiation.

Photomultiplier tubes (PMTs) are highly sensitive detectors of light in the ultraviolet, visible, and near-infrared ranges, converting photons into an amplified electrical signal through a cascade of electron multiplication. They are widely used in scientific research, medical imaging, and industrial applications due to their high gain, fast response, and low noise characteristics.
