“…A suitable state-of-art electronic readout system is required to achieve X/γ signal differentiation, for low noise and good processing time performance. These requirements are met by a custom designed Application Specific Integrated Circuit (ASIC), named ORION [9][10][11] designed at the University of Pavia and Politecnico di Milano (PoliMi) which is capable of handling and discriminating the signals from both detector operating modes (i.e., direct interation in the SDDs or interaction in the scintillators).…”

The functionality and experimental performance characterization of the latest four channel version of ORION ASIC, a very low noise multichip read out and processing electronics customized for the X and Gamma Imaging Spectrometer (XGIS) instrument onboard the Transient High-Energy Sky and Early Universe Surveyor (THESEUS) mission, is presented. XGIS is a set of two coded-masked wide field deep sky cameras using monolithic SDDs (Silicon Drift Detectors) and CsI:Tl (Thallium doped-Cesium Iodide) scintillator-based X-γ ray detectors. This paper highlights the design, working principle and the expected performances of the XGIS, on a small scale 2×2 prototype. Furthermore, the evolution timeline of different versions of ORION with detailed performance observations and analysis for spectroscopic resolution, electronic noise and the operational linear energy ranges of both X and the γ processors of the four-pixel ASIC version bonded to a 2×2 SDD array are emphasized. Each 2×2 SDD array element is electrically and dimensionally equivalent to single elements of the THESEUS 8×8 SDD array.
