Photomultiplier tube(PTM)
it can detect a weak flash of light and estimate the amount of light .The principle of operation (fig(4)) a light photon released electron at the photocathode that is accelerated to the first dynode where it caused several more electrons to be emitted and these electrons are accelerated to the second dynode which is more positive than the first and farther multiplication takes place. Most PTM have 10 dynodes so electron multiplication of 105 to 106 times and it need a high voltage (~1000 V)
