Summary: CryoFree, a gamma-ray spectrometer, has been built and successfully tested.
This instrument is based on a planar germanium semiconductor detector and is optimized
for high-resolution spectroscopy in the range of a 30 keV to a few hundred keV to detect
U and Pu. The spectrometer is cooled with a mechanical cryocooler that obviates the
need for liquid cryogen. Furthermore, the instrument is battery powered. The
combination of mechanical cooling and battery operation allows high-resolution
spectroscopy in a highly-portable field instrument. A description of the instrument along
with its performance is given.
