Paper Abstract

This paper describes the development of cylindrical coplanar grid CdZnTe detectors for gamma ray spectroscopy. Cylindrical detector offer a number of advantages over established designs. For example, grid structures for cylindrical detectors are simpler than those for rectangular designs. The goal of our work is to design a cylindrical coplanar grid detector with excellent resolution at low- and high-energy. Information on detector design and manufacturing is presented. Six detectors are characterized. The pulse height resolution of the best detector is 13.5 keV full width at half maximum at 662 keV and 5.5 keV FWHM at 122 keV.
