Photon Detectors: Photomultiplier tubes versus Photodiodes

The photomultiplier tube has been used for signal detection in flow cytometers since the introduction of the technique. New technology, Avalanche Photodiodes, have been introduced that provide enhanced capabilities. In this part of our Magic Inside video series, you will be transported inside of these detectors to learn how photons are converted into electronic signals and compare and contrast attributes of both detector types.
