Abstract

An amplitude dependence of afterpulses caused by an ion feedback on the main pulse amplitudes in a photomultiplier tube is studied. It has been found that a maximal afterpulse amplitude-to-maximal main pulse amplitude ratio is inversely proportional to the main pulse amplitude. It has been discovered that the feedback-ion intensities are proportional to the charge released by main pulses at the output of the photomultiplier tube. These facts prove that a detection process of single ions can explain the maximal amplitudes of afterpulses.
