What is the mechanism of operation of the Photomultiplier Tube?
There are two principles involved the the photomultiplier tube. First is the photoelectric effect, where photons interact with the photocathode, creating electrons. Second, is secondary emission, where the electrons are multiplied over and ... Read More »

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. Read More »

Why can't we make photomultiplier tubes as an energy resource?
I haven't done any research but I'm going to make a complete guess and say somethings off with either the control, the current, the power, or things like that. Just a guess :) Source(s): Thinking about problems with almost abstract energy r... Read More »

Answers to Other Common Questions
A photomultiplier has a cathode where the photon emits an electron, followed by several "dynodes", each of which multiplies the single electron by an average factor in the general range of 2 to 100, depending on the voltage applied to it. A...
