Possible applications of CdTe detectors to high energy astronomy.
Abstract
The current missions SIGMA and CGRO are demonstrating that the next generation of high-energy astronomy instruments should provide both fine spectroscopy and imaging. Today, room temperature solid state materials are opening the possibility of realizing high efficiency position sensitive detectors (PSD) operating between about 10 keV and about 5 MeV. Particularly promising is cadmium telluride, which could offer the possibility of constructing highly compact segmented PSD's with pixel sizes down to a few square millimeters and good energy resolution. This type of detector array could easily be coupled with a coded aperture in order to achieve the required angular resolution. Two possible designs of this type of PSD are presented and discussed.
