Into darkness: From high density quenching to near-infrared scintillators

In many aspects measurement of the α/β ratio has advantages over other methods. It provides higher precision and higher density of excitation than is available with Compton or photoelectric effect electrons. It has been shown that the α/β ratio follows the same trends and patterns as previously found for nonproportionality of electron/ gamma...

Time-resolved gamma spectroscopy of single events

In this article we present a method of characterizing scintillating materials by digitization of each individual scintillation pulse followed by digital signal processing. With this technique it is possible to measure the pulse shape and the energy of an absorbed gamma photon on an event-by-event basis. In contrast to time-correlated single...
