Abstract :
A GUI application named CZT Simulator based on ROOT is developed to study pixelated CZT detector. The parameters taken into account include detector size, pixel size, electronic noise, threshold and so on. Ansoft Maxwell is used to calculate the electric field and the weighting potential of the detector. Geant4 is used to obtain the initial energy deposition data. Induced Current Calculator package is used to simulate the response of the detector. Compton scattering effect, carrier trapping, corner and edge effect are investigated to understand how the spectrum is formed. A 4 × 4 pixelated, 10 × 10 × 10mm3 CZT detector is simulated, fabricated and tested.
