The article reports that pulse height analyzer (PHA) was originally developed to measure the amplitude of pulses from nuclear radiation detectors. It is therefore an important part of most systems that are used for analyzing event energies from alpha, beta, gamma, and X rays, for analyzing the time between events, and for ensuring orderly storage of count information in sequential time periods. PHAs are ideally suitable in system configurations for experimental and production applications in nuclear, chemical, medical, and materials analyses. PHAs are an outgrowth of the single-channel analyzer, which counted amplified electrical signals of a given pulse height created by nuclear events occurring within a detector. The amplitude was accepted by a peak voltage within a "window" or channel defined by two discriminators-referred to as a differential discriminator. |
