Abstract

The detector-grade crystal was manufactured by modify bridgman method in Yinnel Tec. The resistivity of the CZT is ∼1011(Ω•cm). Their high resistivity caused low leakage current. We fabricated 3x3 pixel array detector. We measure spectral response of the detector, through Gaussian Fitting, The energy resolution of the detector is 23.7%(28.9 keV FWHM) for 122 keV 57Co and 17.9%(117.8keV FWHM) for 662 keV 137Cs, respectively. The spectrum is gauss distributing. Low energy band tail is sharp. It shows that effect of hole is weak. the detector has no polarization.
