Abstract
The drift strip method for improving the energy response of a CdZnTe (CZT) detector to hard X and gamma rays is discussed. Results for a 10x10x3 mm3 detector crystal demonstrate a remarkable improvement of the energy resolution. The full width at half maximum (FWHM) is 2.18 keV (3.6%), 2.45 keV (3.0%), 2.86 keV (0.8%) and 3.89 keV (0.6%) at 60 keV, 80 keV, 356 keV and 661 keV, respectively. The resolution is limited by electronic noise below 100 keV.
