A compact detector system matched to small size CdZnTe detectors has been developed for low energy γ-ray measurement.The linear array system has 16 channels of low noise nuclear read-out electronics.The principle of operation and the results of the system are presented.At room temperature
for 241Am 59.5 keV γ-ray
the total noise of each channel detector system is about 8.9 keV(FWHM)
