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 10 x 10 x 3 mm(3) detector crystal demonstrate a remarkable improvement of the energy r esolution. The full width at half maximum (FWHM) is 2.18 keV (3.6%), 2.45 k eV (3.0%), 2.86 keV (0.8 %) and 3.89 keV (0.6%) at 60, 80, 356 and 661 keV, respectively. The resolution is limited by electronic noise below 100 keV. (C) 2001 Elsevier Science Ltd. All rights reserved.
