Development of a Hard X-Ray Polarimeter for Solar Flares and Gamma-Ray Bursts
We describe recent work on the development of a Compton scatter polarimeter for measuring the polarization of hard X-rays (100–300 keV) from astrophysical sources. Results from measurements with a laboratory prototype are summarized, along with comparisons to Monte Carlo simulations. We also present our latest design concept, which envisions a complete polarimeter module on the front end of a 5...
متن کاملThe Development of GRAPE, a Gamma Ray Polarimeter Experiment
The measurement of hard X-ray polarization in γ-ray bursts (GRBs) would add yet another piece of information in our effort to resolve the true nature of these enigmatic objects. Here we report on the development of a dedicated polarimeter design with a relatively large FoV that is capable of studying hard X-ray polarization (50-300 keV) from GRBs. This compact design, based on the use of a larg...
متن کاملPOLAR: a space borne GRB polarimeter
The direction and the level of polarization of high energy photons emitted by astrophysics sources are valuable observables for the understanding of the corresponding emission mechanisms, source geometry and strength of magnetic fields at work. POLAR is a novel compact space-borne detector conceived for a precise measurement of hard X-ray polarization and optimized for the detection of Gamma-Ra...
متن کاملPOLAR: a Gamma-Ray Burst Polarimeter onboard the Chinese Spacelab
POLAR is a novel compact space-borne Compton polarimeter conceived for a precise measurement of hard X-ray polarization and optimized for the detection of the prompt emission of Gamma-Ray Bursts (GRB) in the energy range 50−500 keV. A first detailed measurement of the polarization from astrophysical sources will lead to a better understanding of the source geometry and of the emission mechanism...
متن کاملSearch for fast optical activity of SGR 1806 - 20 at the SAO
The region of SGR 1806-20 localization was observed during its gamma-ray activity in 2001. The observations have been performed on the 6-meter telescope of the Special Astrophysical Observatory, using the Panoramic Photometer-Polarimeter (PPP). The search for variability was performed on the 10 10 s time scale, and its results were compared to the properties of corresponding x-ray flares.
