Multilayer mirror-based soft x-ray polarimeter for astronomical observations

Marshall, Herman L.; Narendranath, Shyama; Panini, Singam S. +3 more

A simple design of a soft x-ray polarimeter using multilayer mirrors is presented. A multilayer mirror acts as a linear polarization analyzer for x-rays at incidence angles close to the Brewster angle. The instrument consists of an x-ray concentrator, a set of multilayer mirrors placed at 45 deg from the optical axis, and a detector at Nasmyth foc…
