Contribution of the Astronomical Observatory of Strasbourg to the SVOM mission.
The SVOM mission (Space-based multi-band astronomical Variable Objects Monitor) is a Franco-Chinese mission dedicated to the study of the most distant explosions of stars, the gamma-ray bursts. It will be launched at the end of 2022 by the Chinese Long March 2C rocket from the Xichang launch base.
It is the result of a collaboration between the two national space agencies, CNSA (China National Space Administration) and CNES (Centre national d’études spatiales) with the main contributions of the laboratories of the IRFU (Institut de recherche sur les lois fondamentales de l’univers ) and the IRAP (Institut de recherche en astrophysique et planétologie) for France and of the National Astronomical Observatory (NAO) and the Institute of High Energy of Beijing (IHEP) for China…
The mission includes 4 main instruments of which 2 are French (ECLAIRs and MXT) and 2 are Chinese (GRM and VT):
- The ECLAIRs telescope to detect and locate gamma-ray bursts in the X-ray and low-energy gamma-ray band (from 4 to 250 keV).
- The MXT telescope (Microchannel X-ray Telescope) for the observation of gamma-ray bursts in the soft X-ray range (from 0.2 to 10keV)
- The GRM (Gamma Ray Burst Monitor) gamma-ray detector to measure the spectrum of high energy bursts (from 15 keV to 5000 keV).
- The VT telescope (Visible Telescope) operating in the visible range to detect and observe the visible emission, produced immediately after a gamma-ray burst
The Observatory is in charge of the development, the deployment and the maintenance of the following items:
- Ground processing pipeline of the MXT X-ray camera data
- Calibration database for the whole mission
- Scientific products descriptor for the whole mission
- Module interfaces
The team working on this project is composed of L. Michel, P. Guillout, A. Lorang, P. Maggi and C. Motch
