The goal is to integrate this telescope into an array of similar instruments, leveraging its lightweight design, earthquake resistance, and established Davies-Cotton configuration. Additionally, its optical system is designed to function without a protective dome, allowing it to withstand the harsh atmospheric conditions typical of mountain environments above 2000 m a.s.l. The SST-1M utilizes a fully digitizing camera system based on silicon photomultipliers (SiPMs). This camera is capable of digitizing all signals from the UV-optical light detectors, allowing for the implementation of various triggers and data analysis methods. We detail the process of designing, prototyping, and validating this system, ensuring that it meets the stringent requirements for gamma-ray detection and performance. An SST-1M stereo system is currently operational and collecting data at the Ondřejov observatory in the Czech Republic, situated at 500 m a.s.l. Preliminary results from this system are promising. A forthcoming paper will provide a comprehensive analysis of the telescope's performance in detecting gamma rays and operating under real-world conditions.</p> Dewey 500.2 34 Département de physique nucléaire et corpusculaire 132 false 1401 Groupe Della Volpe Journal of cosmology and astroparticle physics 2025 02 d8da29bd-f65d-43b8-b52d-aa7f8ab42591 Article (Published version) Public Alispach_2025_J._Cosmol._Astropart..pdf 34161584 application/pdf CC BY-4.0 40236b165642b126ec370ffc2c1a88b9d7775574a7a073dbaec0b58fed9b6766 openAccess Faculté des sciences / Section de physique / Département de physique nucléaire et corpusculaire
