Abstract :
CdZnTe (CZT) capacitive Frisch grid detector has increasingly captured the recent research interests in room temperature gamma-ray detection applications. The geometrical parameters of the detector have an important role in improving the detector performance. In this paper, the design parameters were optimized through finite element simulation, based on a 3-dimensional weighting potential analysis. The optimized parameters with a ratio of L/H of about 80% and d/8r <0.1mm were obtained. In addition, for the same ratio of L/H and d/er, model B with 5times5times10 mm3 could get better performance than model A with 8times8times10mm3
