Descripción

Crystal Eye is a new concept of space-based all sky monitor for the observation of 10 keV $-$ 30 MeV photons exploiting novel detection techniques. It foresees enhanced localization capability and detection power of the astrophysical short-duration outburst phenomena in an unprecedented energy range with respect to other concurrent instruments. The instrument uses the advantage of new detector materials (scintillator crystals) and high-efficiency sensors (like silicon photo multipliers). The primary scientific goal is the detection of the electromagnetic signal from extreme phenomena in the Universe. In order to enhance the understanding about these phenomena through simultaneous multi-messenger study, the satellite will be able to provide real-time alerts with precise location information to both space and ground based experiments. The full scale design of the detector has been optimized and the engineering qualification model is going to be realized at this stage. Furthermore, a scaled down prototype made of three full size pixels is being realized to fly aboard the Space Rider (ESA) in a low-Earth orbit for a tentative life time of two months in 2027, with the aim to characterize the background at the orbit and verify the technology for space use. We present here the instrumental setup and its performances estimated using Monte Carlo simulation of the full detector configuration in a speculative working environment along with prototype tests.
