Affiliation: Raman Research Institute, Bangalore Abstract Type : Poster Abstract Category : Instrumentation and Techniques Abstract : POLIX is an X-ray polarimeter being developed at Raman Research Institute (RRI) for a small satellite mission of ISRO. The instrument is based on Thomson scattering of X-ray photons from a low atomic mass scatterer and subsequent detection in X-ray proportional counters. It works in energy band of 5-30 keV. It will be suitable for X-ray polarisation measurement in about 50 brightest X-ray sources, with a Minimum Detectable Polarisation (MDP) of 2-3%. The accretion powered X-ray pulsars, black hole X-ray binaries, rotation powered pulsars, non-thermal SNR and AGNs will be the prime targets for this mission. A laboratory model of the instrument has been made and tested successfully, an engineering model has been designed and fabrication of the same is in the final stages. Tests towards engineering model qualification are in progress. We present different aspects of the instrument design, sensitivity for polarisation measurement, current status of development and qualification test results. |
