Query: Silicon photomultiplier-based Compton Telescope for Safety and Security
  (SCoTSS)   A Compton gamma imager has been developed for use in consequence management
operations and in security investigations. The imager uses solid inorganic
scintillator, known for robust performance in field survey conditions. The
design was constrained in overall size by the requirement that it be person
transportable and operable from a variety of platforms. In order to introduce
minimal dead material in the path of the incoming and scattered gamma rays,
custom silicon photomultipliers (SiPMs), with a thin glass substrate, were used
to collect the scintillation light from the scatter layers. To move them out of
the path of the gamma rays, preamplification electronics for the silicon
photomultipliers were located a distance from the imager. This imager, the
Silicon photomultiplier Compton Telescope for Safety and Security (SCoTSS) is
able to provide a one-degree image resolution in a plus-minus 45 degree field
of view for a 10 mCi point source 40 m distant, within about one minute, for
gamma-ray energies ranging from 344 keV to 1274 keV. Here, we present a
comprehensive performance study of the SCoTSS imager.
