PROJECT TITLE : Hard X-Ray Capillary Optics to Provide a High Efficiency Broad-Band Concentrator in the Spectral Range of 10 keV to 100 keV

TECHNICAL ABSTRACT (LIMIT 200 WORDS)

Stellar objects and events, radiating in the broad spectral range from 30 to 100 keV, can not be adequately observed using current technology x-ray optical devices. Mirror telescopes based on variations of Wolter's design rapidly become inefficient, and prohibitively long for spaceborne experiments. Therefore an innovation in instrument capability for this energy regime would enable a wealth of knowledge to be obtained about the Universe and fundamental astronomical physics. Recently, transmission studies using polycapillary fibers indicate that their use in x-ray telescope would remarkably improve measurement capabilities over the range from 10 to 100 keV, while increasing the collecting areas (100 - 3000 cm2), and reducing the instrument focal lengths to < 4 m. This Phase I research effort would develop and characterize the polycapillary fibers necessary for a compact, broad-band, x-ray concentrator for efficient focusing hard x-ray radiation during NASA space flight missions. An x-ray concentrator would be designed to determine the feasibility and increased benefit from utilizing polycapillary fiber optics. Our research team includes X-Ray Optical Systems, Inc., the world's leader in the development polycapillary optic technology, and The Center for X-Ray Optics, the leading facility in world the for basic research with polycapillary optics.
POTENTIAL COMMERCIAL APPLICATIONS
Beyond the impact of developing better hard x-ray optics, several technologies could immediately derive significant benefit from the development of hard x-ray polycapillary optics including; dual-energy digital subtraction angiography, mammography, and x-ray tomography. Furthermore, lenses that operated in this energy range could readily be used in material analysis techniques.
