In situ applications require a very high level of portability of
high-resolution spectrometric equipment. Usage of HPGe detectors for
radioactivity measurements in the environment or for nuclear safeguard
applications, to combat illicit trafficking of nuclear materials or uranium
and plutonium monitoring in nuclear wastes, has become a norm in the recent
years. Portable HPGe-based radionuclide spectrometer with electrical cooling
has lately appeared on the market for in situ applications. At the same time
deterioration of energy resolution associated with vibrations produced by
cryocooler or high weight of the instrument, short time of autonomous
operation and high price of these spectrometers are limiting their usage in
many cases. In this paper we present development results of ultra compact
hand held all-in-one spectrometer for in situ measurements based on HPGe
detector cooled by liquid nitrogen without listing the above disadvantages.
