Description
The Crystal Eye is an innovative space based X and γ-ray future all sky monitor active from 10keV up to 30MeV, an energy range still under-explored. The full detector consists of a 40cm diameter hemisphere made by 112 pixels. It combines a wide FOV, a good sky localization capability and a large effective area, 6 times higher than Fermi-GBM at 1 MeV. Each pixel consists of two scintillating LYSO crystals, read by SiPM-arrays, equipped with segmented anticoincidence for photon tagging and charged Cosmic Ray (CR) identification. Preliminary studies about the materials to be used and the DAQ concept has been made thanks to a breadboard prototype. Recently, an Engineering Model, consisting of 3 pixels, has been realized to perform further tests and optimize the parameters for the realization of the Crystal Eye pathfinder for the Space Rider mission. Three operation mode are planned: a space and an earth observation mode and a calibration mode. Decisions taken on materials, geometry and electronics will be presented together with the first results of the calibration procedure, based on the emission spectrum of LYSO crystals, and the first measurements performed with radioactive sources.
