Development of the POLAR experiment for the gamma-ray bursts polarimetry
Abstract
The polarimetric data taken together with lightcurve and spectral data may provide a powerful probe of the nature of sources and emission mechanisms of Gamma-ray Bursts (GRBs). We would like to know if most of the GRBs are strongly polarized. There were several reports of detections of linear polarization but more accurate observational data and the statistical study are still needed. The POLAR experiment is a space-born polarimeter designed for measurement of γ-ray in the energy range 50-500 keV. The detector was mounted onto the Chinese Tiangong 2 space station in 2016. The preflight status of the POLAR experiment has been presented in the talk.
