“…The first measurement gave us information about the LYSO activity and response and solved some concerns about the measurements in [9], and so a very important hint on the best treatment for the surfaces. The MPPC-arrays are all working at 2V overvoltage.…”

“…Each array is composed by 16 MPPCs, we read each quadrant by setting an OR circuit among the four anodes and cathodes. This will ensure redoundancy as well as high and low gain channels [9]. All the channels are readout by a custom DAQ board based on the CITIROC1A chip for the signal processing and on the Zynq 7020 for the trigger logic, programmed by Nuclear Instruments SRL [10].…”

“…The first is based on a majority (> 3 quadrants) and the OR of the crystals, while the observation mode is realised by the AND of the crystals and the same majority. Preliminary tests have been performed by means of a commercial DAQ board (CAEN A1702), to define the crystal performances [17] and the trigger logic parameters [18], on a three pixels prototype made of LYSO crystals, manufactured by several companies:…”

Crystal Eye idea comes from the analysis of two gravitational waves events: GW170817 and GW190425. Both events were referred to neutron star mergers. In the first case Fermi-GBM and INTEGRAL claimed the detection of a short Gamma Ray Burst (GRB 170817A) and in order to follow up and target the GW electromagnetic counterparts, a huge effort has been made by other satellites and ground-based experiments. In the second case, only INTEGRAL claimed the detection of a faint GRB (GRB 190425) while Fermi satellite was in Earth occultation. Crystal Eye is a space-based X and γ ray all-sky monitor sensitive in the 10 keV - 30 MeV energy range. In its baseline configuration, it consists of a hemisphere, made by 112 pixels, with a wide (about 6 sr) field of view (FOV), a full sky coverage and a very large effective area (6 times Fermi-GBM at 1 MeV) in the energy range of interest. Given the pixel structure – a two-layer crystal scintillator and a plastic scintillator veto layer – and the hemispherical design, Crystal Eye concentrate the pointing capability of a γ-ray telescope and the sky coverage of an all-sky monitor in a single detector. Moreover, the use of Silicon Photomultiplier (SiPM) at the place of traditional PMs, besides being a challenge for their qualification for space missions, allows a more compact and less power-consuming design. A Crystal Eye pathfinder has been designed and realized to be tested in view of the mission on the Space Rider by ESA. The prototype is made by 4 pixels. The mission is aimed at testing in the space environment the LYSO crystals, the MPPC-arrays and the DAQ board.
