  1. Small Business Innovation Research Polyimide X-ray Filters Optimized for Strengthat Cryogenic TemperaturesLuxel CorporationFriday Harbor, WA • INNOVATION This SBIR optimized the strength of polyimide thin film x-ray filter substrates at cryogenic temperatures, allowing thinner windows, higher internal pressure, or a larger safety factor on burst thereby improving mission performance. • ACCOMPLISHMENTS • High resolution x-ray spectroscopy using microcalorimeters requires windows that can survive launch loads and long term operation at cryogenic temperature. • Polyimide windows from 450 to 9115Å were burst tested at room temperature (300K), liquid nitrogen temperature (77K), and liquid helium temperature (4.2K). • By optimizing the processing parameters, especially cure cycle time, temperature, and atmosphere, an average burst strength increase of 36% was obtained. COMMERCIALIZATION • Polyimide films fabricated using the optimized processing parameters are now commercially available from Luxel. Cryogenic Burst Strength Testing Apparatus • GOVERNMENT/SCIENCE APPLICATIONS • The filters developed during this SBIR offer improved mission performance for future astronomy experiments at lower cost. • Polyimide film, optimized for cryogenic temperature, will be used as pressure windows for laser targets. For example, the National Ignition Facility (NIF) requires windows that operate at 18K with a 1 atmosphere differential.
