These electrons are accelerated by a positive electrostatic field and fall upon a metal surface where they emit secondary electrons that are again accelerated to generate more electrons at the next metal surface. A photomultiplier tube (PMT) has very low noise levels allowing the current generated by incident light to be multiplied over a million times to where individual photons can be detected.
