The airborne gamma ray spectrometer system GammaFLY consists of 16 NaI(Tl) crystals with a total volume of 1024 cubic inches (16.78 liters).
The NaI(Tl) crystals are coupled to the fully integrated 16 channels multi-channel analyzer CAEN SD7740 with special digital pulse processing firmware.
CAEN SD7740 also provides 16 channels of 4 kV High Voltage to bias the NaI(Tl) Detectors. Data logging is available in both data list with time stamp and energy of the single event, and energy spectrum up to 4096 channels with user selectable full range from 20 keV to 10 MeV.
The method of Full Spectrum Analysis with Non-Negative Least Square is used to precisely analyze the contribution of different natural and man-made isotopes, as 40K, 137Cs, and daughter products of 238U and 232Th
