This photomultiplier tube has a large end window. A scintillation crystal is placed on this window, and the photmultiplier detects the flashes of light when atomic particles pass through the crystal. These flashes convert to electrons, which are accelerated through a series of dynodes at about 100V per dynode. At each dynode, the accelerated electrons crash into the anode and splash out additional electrons. Thus one electron may become 1,000,000 electrons at the end of the train of dynodes.
