[ 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...
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,...
[ Astronomický ústav AV ČR, 2022-02-18] Mirrors for the second SST-1M (Small-Sized Telescope) telescope with a primary mirror diameter of 4.3 meters designed for the detection of Cherenkov radiation are currently being installed at the Ondřej observatory. Energetic electromagnetic radiation, such as X-rays or gamma rays, does not pass through the atmosphere. When a gamma photon passes through the atmosphere (as well as when a charged particle with high energy passes), a shower of secondary particles and Cherenkov radiation is produced. These sensitive telescopes with high temporal resolution can detect this Cherenkov radiation from the atmospheric shower. The sources of...
Two unique Cerenkov telescopes (SST-1M) are installed at the Astronomical Institute of the CAS in Ondrejov. The telescopes are designed to study gamma rays with extremely high energy coming from sources in our Galaxy or in more distant places in the Universe. This is an international project involving scientists from the CAS, Palacký University in Olomouc and teams from Switzerland and Poland. The optical design of SST-1M is based on the Dawies-Cotton optical design. The 4 m diameter mirror of the telescope is divided into 18 segments and a fully digital camera composed of 1296 pixels, each with a sampling...
