A CZT 3D imaging spectrometer prototype with digital readout for high energy astronomy

The scientific challenges still open in hard X-rays and γ-rays astronomy require the development of new instrumentation able to overcome the sensitivity limits of the present one. Among the technologies currently under study to cover the energy range between several tens of keV and one MeV, the development of telescopes equipped with broadband Laue lenses associated with focal planes with high spectroscopic and imaging performance represents an extremely promising solution. With this perspective, we report on the development and the first spectroscopic characterisation results of an X/γ rays detection system (10-1000 keV) based on CZT spectrometers with spatial resolution in three dimension…
