Abstract
A phoswich detector having two or more scintillators is disclosed, in which at least one optical filter is provided between the scintillator farthest from a photomultiplier and the scintillator nearest to the photomultiplier. The detector is capable of reducing the pulse height of signal from the scintillator to an arbitrary level and extending the rise time of the pulse to some extent.
