PNNL's HpGe X-cooler poptop detector
Model: GEM120P4
The above model number indicates that the detector has an relative efficiency of 120% with respect to a 3" x 3" NaI crystal, a resolution of 1.3 keV for 122 keV photons, resolution of 2.1 keV for 1.33 MeV photons, a peak to compton ratio of 86:1, and end cap diameter of 0.108 mm.
serial #: 44-TP41387A
GEM model => p-type => Usually a positive HV bias
GMX model => n-type => Usually a negative HV bias
