Overview of Segmented Glass Optics Development for the Constellation-X Hard X-ray Telescope

چکیده
We report recent work on segmented glass optics for the Constellation-X Hard X-ray Telescope. This effort seeks to both improve the figure of the free-standing glass substrates, and to refine a newly-developed mounting technology for the substrates. We discuss metrology on recently characterized glass shells both unmounted and mounted. We also present plans for several prototype optics to be constructed in the upcoming year.

Progress towards Meeting the Constellation-X Performance Goals using Segmented X-ray Mirrors
We present an overview of our recent progress toward the development of segmented X-ray mirrors for the Constellation-X mission. Our reference design incorporates thin glass reflector substrates, with axially curved X-ray reflecting surfaces applied via epoxy replication. Alignment is accomplished via a precision structure incorporating ultraprecise etched Si alignment microstructures (as descr...
متن کاملFast optical metrology of the hard x-ray optics for the High Energy Focusing Telescope (HEFT) †
We describe a fast figure metrology system designed for the several thousand mirror quadrants in the High Energy Focusing Telescope (HEFT) balloon experiment. HEFT's multilayer coated hard x-ray optics will have ~ 1 arcminute HEW and operate at 20-80 keV. The optics are a conical approximation to the Wolter-I configuration. Our automated system can measure the axial figure error, in-phase and o...
متن کاملFABRICATION OF Pt/C MULTILAYER-COATED THIN FOIL MIRRORS FOR HARD X-RAY TELESCOPE LOADED IN ASTRO-H SATELLITE
INTRODUCTION In future satellite missions for X-ray astronomy, hard X-ray imaging will become one of the major observation techniques. It allows astronomers to observe the distribution of hard X-ray objects in the Universe with a high sensitivity. Since hard X-rays can penetrate thick absorbing materials, astronomers are able to discover many massive black holes embedded in thick gas. High-ener...
متن کاملResolving the 10-40 Kev Cosmic X-ray Back- Ground with Constellation-x
The energy density of the Cosmic X–ray background (XRB) peaks around 30 keV (see Figure 1), an energy not yet probed by focussing imaging instruments. The first hard X–ray telescope due to fly on a space mission will be that on board Constellation–X. The imaging capability, besides providing an improvement of several orders of magnitude in sensitivity over current passively collimated detectors...
