A photomultiplier tube works by converting incoming light photons into an electrical signal. When light hits the photocathode of the tube, it emits electrons through photoelectric effect. These electrons are then multiplied by a series of dynodes within the tube, resulting in a larger current that is proportional to the intensity of the incoming light. This amplified signal can then be measured and analyzed.
What else can I help you with?
Why can photomultiplier tubes not be used with infrared radiation?
A PM tube doesn't operate in that wavelength. A PM tube detects light which is generated from a scintillator. The scintillators are typically designed to scintillate as a result of a reaction with ionizing radiation.
What is the main detector of a scintillation counter?
the main detector of a scintillation counter depends on the calculating factor that you depict on using in your scintillation.
How does a gamma counter work?
A scintillation counter measures ionizing radiation. The sensor, called a scintillator, consists of a transparent crystal, usually phosphor, plastic (usually containing anthracene), or organic liquid (see liquid scintillation counting) that fluoresces when struck by ionizing radiation. A sensitive photomultiplier tube (PMT) measures the light from the crystal. The PMT is attached to an electronic amplifier and other electronic equipment to count and possibly quantify the amplitude of the signals produced by the photomultiplier.
What is photoemissive cell?
A photoemissive cell (also known as a photomultiplier tube) is a type of light detector that converts light photons into an electric signal. It consists of a photosensitive cathode that emits electrons when struck by photons. These electrons are then amplified through a series of dynodes to produce a measurable output signal.
An instrument used for detection of light?
Spectroscope. Very fun and interesting activity.
What types of machinery use photomultiplier tubes?
Photomultiplier tubes were used is earlier forms of the fax machine, photocopiers and drum scanners. The photomultiplier tube was for scanning the document.

Where can one find out more information about a photomultiplier?
There is a website called HAMAMATSU (yes, the website shows the name in all capital letters), that has an article on what a photomultiplier does, complete with a diagram.

How does a tube well works?
a well made by driving a tube into the earth to a stratum that bears water
How does the laser works?
The laser works by reflecting and amplifying a beam of light through a tube of mirrors.
Why is the grasshoppers body plan often called a tube within a tube?
Grasshoppers basically have a tube which runs from the mouth to the anus that works as its digestive tract.
What is the pollination tube?
A pollination tube, or pollen tube, is a thin tube that is a part of the male gametophype. It is found in seed plants and works by acting as a sort of conduit to transport gamete cells.
