X-ray polarimeters

Abstract

X-ray polarimetry is entering a new era, thanks to the significant technological developments allowing the design of new and very sensitive experiments. In this chapter we briefly remark the importance of the polarimetric diagnostic tools in the investigation of the physics of neutron stars, and provide an overview of both classical and new techniques for X-ray polarimetry in astronomy. Finally, we report about the characteristics and scientific potential of the focal plane X-ray polarimeters that have the highest chances to be flown over the next decade.
