Paper Abstract

X-ray Timing and Polarization (XTP) satellite, by using focusing optics and advanced detector technology, is dedicated to the study of Black Hole, Neutron Star, Quark Star and the physics under extreme gravity, density and magnetism. With a detection area of ~1 square meter and a combination of various types of X-ray telescopes, XTP is expected to make the most sensitive temporal and polarization observations with good energy resolution in 1-30 keV. We present a recent overview on segmented glass optics for XTP Telescope. This work is looking for improvement of the figure of the free-standing glass substrates, enhancement of quality of grazing incident depth-graded multilayers and a mounting technology for the substrates. We discuss metrology on glass figure, X-ray reflectivity and scatter of grazing incident depth-graded multilayers, and mounted structured optics. We also present plans for several prototype optics to be constructed in the upcoming year. Begin the abstract two lines below author names and addresses. The abstract summarizes key findings in the paper.
