Paper Abstract

A small prototype cadmium telluride (CdTe) detector optimized for the detection of gamma-rays having an energy of the order of 500 keV was designed. This detector was arranged as an array of 5x5 CdTe crystals, each having dimensions of 2x2x10 cu mm, and was constructed primarily in order to verify its technical feasibility and performances. The initial aim in developing this type of detector was for use in space applications such as measurement of annihilation radiation (511 keV photons) from the galactic center and possibly from extragalactic objects as for example AGN's (Active Galactic Nucleus). Many other applications may also benefit from the use of CdTe position sensitive detectors, in linear or square configuration, such as nuclear medicine diagnostics, nondestructive testing in industrial quality assurance processes, and safety inspection and controls.
