Laboratory Verification of Instrumentation for Soft X-Ray Polarimetry

Project Start Date March 2012

The objective of this program is to develop instrument components that can be used to measure the polarization of astrophysical X-ray sources at energies below 1 keV. We propose to obtain components such as laterally graded multilayer coated mirrors that can be qualified for space use, assemble them in a vacuum chamber, and test the system with unpolarized and polarized X-rays. Our plan provides a development path to incorporate polarimetry as an integral part of future X-ray astronomy missions. We would use the laboratory work described here to demonstrate the function of hardware that we will propose for flight observations.
