Dual anode contact geometries for x-ray and gamma-ray spectroscopy and 3D localization
We report on the continued development and testing of unique types of Cadmium Zinc Telluride (CZT) detectors.
Using large volume (10×20×20 mm3) CZT crystals, we contact various "dual anode" detector designs. We
incorporate a segmented cathode with five regions so that the charge on all seven contacts can be used to
determine the energy and the 3-D interaction location of detected X-ray and gamma-ray photons. We describe
the status of the detector development program, emphasize strengths and weaknesses of the different contact
configurations, and discuss possible applications of Dual Anode Detectors in radiation detection applications.
