研究目的
To explore the polarization of celestial sources in the 2–8 keV energy band, including imaging, timing, and spectroscopic capability, with the Gas Pixel Detector at the focal plane of the telescope.
研究成果
The IXPE mission is a new NASA mission dedicated to X-ray polarimetry. It will explore the polarization of celestial sources in the 2–8 keV energy band, and will include imaging timing and spectroscopic capability. The heart of the mission is the Gas Pixel Detector, developed at INFN-Pisa, that will be placed at the focal plane of the telescope.
研究不足
The main difficulty inherent to this approach is the very small path length of the photoelectron, which even in a light gas can be of the order of few hundred μm, and the reconstruction of its direction of emission is a highly non-trivial problem.
