The S4 (Space-borne SiPM-based Single-photon Sensor) is an instrument designed for single-photon detection in Low Earth Orbit (LEO) using Silicon Photomultiplier (SiPM) technology. The instrument, currently under developed by the LabOSat group (UNSAM), is expected to launch on Q2 2023 as a secondary payload of a commercial Earth-observation satellite. Beside the increase of the Technology Readiness Level (TRL) of SiPM sensors for space applications, the S4 instrument will be a pathfinder for Ground-LEO single-photon communications and fundamental Physics experiments that require single-photon detection.
In this talk we will describe the S4 instrument, focusing on the Analog-Front End (AFE) and SiPMs subsystem. Particularly, we will present the characterization performed at the SPOCK (Single PhOton Calibration stand at KIT) laboratory at the Institute of Astroparticle Physics (KIT), including studies on the performance of the AFE board and sensors at different temperatures, SiPM overvoltages and illumination conditions.
