Zusammenfassung: | The finite–element analysis was done to optimize position-sensing coplanar grid electrode geometry. CdZnTe crystals manufactured by PAM-XIAMEN with customized electrode geometry have been tested. After digitizing pre-amplifier signals, trapezoidal digital filter was adopted to enhance the signal to noise ratio. Energy resolution of 2.7% FWHM at 662 keV γ-ray energy was obtained. The measured results show the dramatic improvement with position-sensing technique. |
