The multichannel pulse height analyzer is a device that will
separate pulses based on pulse height. Each energy range of
pulse height is referred to as a channel. The pulse height is
proportional to the energy lost by a gamma ray. Separation of
the pulses, based on pulse height, shows the energy spectrum of
the gamma rays that are emitted. Multichannel analyzers
typically have 100 or 200 channels over an energy range of 0 to
2 MeV. The output is a plot of pulse height and gamma activity,
as shown in Figure 28. By analyzing the spectrum of gamma rays
emitted, the user can determine the elements which caused the
gamma pulses.
