摘要：

In this paper, the design parameters of the cylindrical capacitive Frisch grid CdZnTe detector were optimized through a finite-element simulation method using ANSYS software, based on a 3-dimensional weighting potential analysis for the first time. The weighting potential distributions of the model with the different ratio of screen length to device height (L/H), insulator thickness (d), insulator relative permittivity (epsilon(r)), electrode areas of anode and the ratio of anode diameter to device height (D/H), were studied. The optimized parameters with an L/H value of 80%, d/epsilon(r) < 0.05 mm, the anode diameter of about 2 mm and a D/H value < 1/2, were obtained. (C) 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
