Last week, members of the SST-1M collaboration gathered at CERN, Geneva, for their annual meeting. This much-anticipated event serves as a crucial platform for the collaboration’s members to meet in person, share insights, and engage in constructive discussions about the current progress, future improvements, and strategic directions of the project. The meeting fostered fruitful exchanges on key technical developments, operational challenges, and upcoming milestones. Participants had the opportunity to present their work, review ongoing initiatives, and collectively explore ways to enhance the performance and scientific impact of the SST-1M mini-array. As always, the spirit of collaboration and innovation was at...
[ Marek Nikołajuk, XXXII IAU, 6-15 August 2024 in Cape Town ] Marek Nikołajuk, member of the SST-1M consortium, presented a poster at the International Astronomical Union General Assembly held in Cape Town, South Africa. The presentation showcased an overview of the telescope and camera design, as well as preliminary results derived from the commissioning data and data analysis. The event provided an opportunity to highlight that the SST-1M mini-array has demonstrated its remarkable potential for conducting detailed astronomical observations. Despite operating under commissioning conditions at the Ondřejov Observatory, the array has already achieved significant results. These achievements pave the...
On October 3rd, a CME (Coronal Mass Ejection) was hurled toward Earth by a powerful X9.1-class solar flare. It struck our magnetosphere a few days later, adorning the sky with colorful swirls. On October 7th, Vlastimil Vojáček captured the aurora borealis, creating a special atmosphere at the Ondřejov observatory.
[ Astronomický ústav AV ČR, Ondrejov 2024-09-27] As part of the Night of Scientists 2024, the Cherenkov telescopes located at the Ondřejov Observatory were also presented to the public. Jakub Juryšek and Dušan Mandát showcased the SST-1M project to attendees and explained related physical phenomena (the formation of particle showers, methods of observation, processing, and more). Last but not least, they answered curious questions from both young and adult visitors from the general public.

[ 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...
[ Bastien Lacave, CTAO Science Symposium, 15-18 April 2024 in Bologna ] Current status and recent results of the SST-1M telescopes were presented at the CTAO Science Symposium in Bologna. Bastien Lacave, member of the SST-1M consortium, presented poster to the general audience, emhasizing achievemts reached with the telescopes operation in stereo mode and future prospects for scientific observations.

[ 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...
