„SST-1M stereoscopic system: Overview and preliminary results”

The SST-1M telescopes are prototypes of small-size single-mirror Cherenkov telescopes, developed collaboratively by Czech, Polish, and Swiss institutions. Their design is based on the Davies-Cotton concept, featuring a 4-meter mirror and an innovative SiPM-based camera. With a 9.42 m² segmented mirror, a 5.6 m focal length, and a wide 9-degree field of view, the SST-1Ms are optimized for detecting gamma rays in the TeV to multi-TeV energy range [1, 2]. The two prototypes have been commissioned at the Ondˇrejov Observatory in the Czech Republic, where their performance is being evaluated in both monoscopic and stereoscopic observation modes [3]. Observations of galactic and extragalactic gamma-ray sources, such as Crab Nebula and Markarian 421, have already led to positive detections [4, 5]. This presentation will provide an overview of the SST-1M project, including its design, development, and current status. Preliminary results from the observation campaigns will also be shown.
