Description
POLIX is an X-ray polarimeter working in the energy range of 8-30 keV and the main scientific payload onboard the upcoming Indian astronomy mission XPoSat (X-ray Polarimeter Satellite) dedicated to study of polarization of cosmic X-ray sources. The polarisation measurements will be performed using anisotropic Thomson scattering of polarised X-rays and this will be enabled by spinning the satellite around the viewing axis of the instrument. Being a dedicated X-ray polarisation mission in this unexplored energy band, POLIX will allow many in-depth investigations of astrophysical processes in neutron star and black hole sources. Along with a description of the instrument, results from simulation of POLIX response to polarised X-ray photons and background will be presented here.
