چکیده

Portable, high-resolution gamma spectroscopy has long been a vital technique in routine safeguards accountancy. The high resolution enables the spectrum analysis to accurately determine the isotopic content of the sample. All currently deployed systems for this application are based on liquid-nitrogen cooled, high-purity germanium (HPGe) detectors, with the spectrum analysis performed on portable PCs. These systems require the ready availability of liquid nitrogen. Detector cool down times on the order of 4 hours add to the difficulty of performing inspections, especially unannounced inspections. Such systems can be demanding of operator skill.
