[ Jakub Jurysek (Institute of Physics of Czech Academy of Sciences), Gamma 2024 – Milano, 2.-6. September 2024 ] The Single-Mirror Small Size Cherenkov Telescope (SST-1M) was developed by a consortium of institutes in Switzerland, Poland, and the Czech Republic. The SST-1M design is based on the DaviesCotton concept, featuring a 4-meter mirror and an innovative SiPM-based camera. It is most sensitive to gamma rays in the TeV and multi-TeV energy bands. Since 2021, two SST-1M prototypes have been commissioned at the Ondřejov Observatory in the Czech Republic, where their performance in both mono and stereo observation modes is being tested....
[ Matthieu Heller (University of Geneva), Gamma 2024 – Milano, 2.-6. September 2024 ] The small-size single mirror telescopes, SST-1Ms, are two Cherenkov telescope prototypes developed by a consortium of Czech, Polish, and Swiss institutions. Featuring a 9.42 m² multi-segment mirror and a 5.6 m focal length, the SST-1Ms offer a broad 9-degree field of view and have proven capable of detecting gamma rays with energies starting from several hundred GeV. The innovative cameras incorporate a compact photo-detector plane with 1296 hexagonal silicon photomultiplier pixels and a fully digital readout and trigger system utilizing 250 MSps FADCs. Currently undergoing commissioning at...
[ Thomas Tavernier (FZU, Prague, Czech Republic), TeVPa 2024 – Chicago, 27. 8. 2024 ] SST-1M is a single-mirror small size Cherenkov telescope prototype developed by a consortium among institutes in Switzerland, Poland, and the Czech Republic. With a 4 meter mirror and a 5.6 m focal length, SST-1Ms have a broad 9 degree field of view and aim to detect gamma rays spanning the energy range of 1 to 300 TeV. The DigiCam camera incorporates a compact Photo-Detector Plane comprising 1296 hexagonal silicon photomultiplier pixels and a fully digital readout and trigger system using a 250 MHz ADC. Two SST-1M...

[ Astronomical Institute of the Czech Academy of Sciences, 5. 4. 2024 ] Two Cherenkov telescopes are located at the Ondřejov observatory. What makes them unique? Cherenkov telescopes are capable of capturing high-energy gamma rays, which cannot be detected in any other way. The telescopes are operated by the Astronomical Institute of the Academy of Sciences of the Czech Republic, the Institute of Physics of the Academy of Sciences of the Czech Republic, the Palacký University in Olomouc, the Henryk Niewodniczański Institute of Nuclear Physics of the Polish Academy of Sciences, the University of Geneva and other institutions of the...
[ SS1-1M consortium, 18. 3. 2024 ] The sst1mpipe repository is used for processing and analyzing data from the SST-1M prototype. We are happy to inform, that the repository is now public, and therefore easily accesible to anyone inside or outside the SST-1M collaboration. It provides tools for low-level data analysis up to DL3, which can be further analyzed using standard tools such as gammapy. Most of the functions and classes are now documented. Currently, two SST-1M telescopes are installed in Ondrejov, Czech Republic, being operated in both mono and stereo observation modes. More about current status of the telescopes, early science and performance can be found in...
Thomas Tavernier (on behalf of SST-1M Consortium), 15. 3. 2024 We report a significant increase in gamma-ray flux from Markarian 421 above 2 TeV. This observation was conducted through stereo observations using the 2 SST-1M IACTs currently in commissioning at the Ondrejov Observatory. The observations extends from 13 March 2024 20:53 to 00:20 UTC resulting in a livetime of approximately 3.3 hours, during which a detection significance of 6.8 sigma was achieved with notable excess up to 7 TeV. The observed flux from Markarian 421 reached levels typically observed from the Crab Nebula, suggesting a substantial increase compared to our...

Jakub Jurysek (on behalf of SST-1M Group), ICRC 2023, Nagoya, Japan, 26. 7. – 3. 8. 2023 The Single-Mirror Small-Sized Telescope, or SST-1M, was originally developed as a prototype of a small-sized telescope for CTA, designed to form an array for observations of gamma-ray-induced atmospheric showers for energies above 3 TeV. A pair of SST-1M telescopes is currently being commissioned at the Ondrejov Observatory in the Czech Republic, and the telescope capabilities for mono and stereo observations are being tested in better astronomical conditions. The final location for the telescopes will be decided based on these tests. In this contribution,...
