A -- LAWRENCE LIVERMORE NATIONAL LABORATORY SEEKS PARTNERSHIPS WITH INDUSTRY TO COMMERCIALIZE HIGH EFFICIENCY INEXPENSIVE REPLICATED X-RAY OPTICAL DEVICES BASED ON SPUTTER DEPOSITION ONTO SUPER-POLISHED REUSABLE MANDRELS SOL CBD99-021 DUE 103199 POC Veronica Lanier (925) 422-6416 Lawrence Livermore National Laboratory (LLNL), operated by the University of California under contract with the U.S. Department of Energy (DOE) has developed the capability to fabricate high efficiency inexpensive replicated x-ray optical devices based on sputter deposition onto a super-polished reusable mandrel. After removal from the mandrel, the device is a tubular shell with an inner surface having the shape and surface smoothness of the mandrel. Depending on the shape of the device, x-rays are focussed, collimated, or otherwise manipulated when they enter one end of the shell, reflect from the inner mirrored surface, and then exit in a new direction. The replicated optics wavelength bandpass is determined by the sputter deposited coating on the internal mirror surface and can be designed to select a specific range of x-ray energies. The high efficiency of the LLNL device results from the high quality of the mirror surfaces, large reflection angle and thus the large solid angle of the tubular structure and the shape fidelity of the replicas compared to more conventional open geometry x-ray optics. Applications include focussing optics for x-ray tube-based sources for x-ray crystallography, focussing or collection optics for x-ray fluorescence analysis, Wolter x-ray microscopes, as well as a broad range of x-ray analytical instrumentation. Note: This is not a procurement. Companies interested in commercializing high efficiency inexpensive replicated x-ray optical devices based on sputter deposition onto super-polished reusable mandrels should provide a written statement of interest that must include the following information: (1) company name and address, (2) the name, address, telephone number, and fax number of a point of contact, (3) a description of your company's expertise and facilities in the relevant technologies. Statements of interest should be sent to: Lawrence Livermore National Laboratory Industrial Partnerships and Commercialization Office P. O. Box 808,L-795 Livermore, CA 94551 Attention: CBD99-021. Please provide your written statement within thirty (30) days from the date this announcement is printed to ensure consideration of your interest in commercializing high efficiency inexpensive replicated x-ray optical devices based on sputter deposition onto super-polished reusable mandrels.
