POLAR is a space-borne hard X-ray Compton polarimeter built by a collaboration of institutes from Switzerland, China and Poland.
Precise detection of the polarization can be an powerful tool to unveil emission mechanisms of e.g. Gamma-Ray Bursts (GRB) or Solar Flares (SF).
POLAR is equipped with an array of 1600 scintillator bars dimensioned for precise measurements of the polarization
of hard X-rays in the energy range from 50 keV to 500 keV.
The instrument was launched into space on September 15th, 2016 on-board the Chinese Space Laboratory TG-2 for up to 3 years long observation period. Telemetry data from its operation in space may reach up tp 50 GB daily.
To store and process such huge amount of data both dedicated hardware and specialized software are required.
Moreover, constant data inflow also requires fully automated and safe guarded data processing. For this purpose a dedicated data center was established at PSI.
We present its design concept%requirements
and structure as well as demonstrate main features
with respect to data processing, quick look utilities and alerting functions.
