This SBIR effort will focus on development of ceramic-based optical materials for laser gain media. Lasers developed from these ceramic materials will enable new accelerator research and development that will lead to new discoveries in high-energy physics. The development approach consists of ceramic nanopowder manufacturing, followed by densification into solid bodies shaped for laser resonator cavities. While proof-of-concept work has been demonstrated at the academic level, it has yet to be elevated to large bodies or commercial status. In Phase I, powder batches of rare-earth-doped sesquiode ceramic materials will be produced using a proprietary process to optimize the performance of the powder. Once powder metrics are achieved, sintered ceramic bodies will be produced and tested for photoluminescence and lasing in an optical cavity. During Phase II and beyond, finished ceramic gain media will be sold to laser manufacturers for incorporation into ultrafast lasers used in accelerators. Key words: Particle accelerator, laser, ultrafast, femtosecond, infrared, dielectric laser acceleration, sesquioxide

Electrical insulation coatings are a preferred alternative to former ceramic wound or braided fiber insulation for Bi2212 round wire in HEP superconducting magnets due to their being 10x thinner giving higher packing factors and current densities), lacking any ill effect on superconductor performance, and having much better heat conductance reducing the likelihood and consequences of unintentional quench). These are applied as green ceramic coatings, and become all-ceramic layers during the Bi2212 reaction heat treat. While enabling a record high field of nearly 34 T in a superconducting magnet point to their benefits, remaining issues with the wire coatings include limited green state scrape resistance, cracking after heat treat, limited dielectric strength, and need for improved thickness control. The aim of the proposed program will be to address improvements in the insulation coating materials and in the coating application process enabling an insulation fully meeting the requirements for HEP as well as fusion, NMR, etc.) magnets employing round wire Bi2212. The proposed effort will address a) increased toughness of the green coating, b) investigation of the cause and elimination of cracking and spalling of the heat treated coating, c) coating application process improvements enabling better thickness control, better quality, coating piece lengths of at least a kilometer, and cost reduction, and d) investigation of the use of alternative ceramic powders enabling higher breakdown strengths. Development of an improved and qualified insulation under this SBIR/STTR program will enable nGimat, the pioneer of this technology, to establish itself as a reliable long-term commercial provider of the insulation in necessary lengths and at affordable price. nGisulate wire-insulation coatings will find immediate application in superconducting magnet- wire that are used to build magnets for major high-energy physics projects around the world. In addition, as the price of the insulation comes down, commercial applications such as Magnetic Resonance Imaging MRI) systems and subsequently automotive wire are also expected to adopt nGisulate technology.

Electric vehicles, including hybrids in the nearer term, are the principal transportation technology by which the United States can become independent of foreign oil, can become energy independent overall, and can effect control over greenhouse emissions. For this to become reality, electric vehicle costs need to come down and performance needs to improve. For electric vehicle motors, the goals are to reduce manufacturing cost to $4.7/kW by 2020 while improving operating performance, including power density, peak power and operating efficiency. This SBIR Phase II project will build on the materials and process accomplishments of Phase I, to develop innovative magnet wire insulation for motor windings that results in increased power density and operating efficiency. This will be achieved by developing a wire insulation that has as much as 10 times higher thermal conductivity so that heat can be better dissipated, meaning that the motor will run cooler and therefore more efficiently. In doing so, all other mechanical, thermal and electrical characteristics of the insulation required by standards will be maintained. With better heat dissipation and efficiency owing to high thermal conductivity insulation, dedicated liquid cooling might be eliminated, contributing to smaller, lower-cost electric drives. The proposed advance in magnet wire insulation will result from the incorporation of high thermal conductivity inorganic particles into high performance polymers. The novel insulation is proposed to be applied by the conventional wire enameling method. Electrical, thermal, mechanical, and chemical property measurements according to NEMA standards for magnet wire will be made to insure that all requirements are met or exceeded. Commercial Applications and other Benefits: In terms of cars scheduled to enter the U.S. market, it appears that President Obamas goal of one million EVs by 2015 will be surpassed. And the Electric Vehicles Initiative forecasts 10 million by 2020. This will create a robust market for motors with the wire insulation being proposed here. In addition to application in EVs, wire insulation technology will also play a key role in larger electric motors that will be used in electric buses and land & amp; marine-based military vehicles. Beyond the traction motor applications mentioned, improved motor/generator systems will also be critical for other energy technologies such as wind turbines.

There is currently no space based laundry technology. Traditional laundry uses a large amount of surfactants, which results in a substantial organic contaminant burden on downstream wastewater processors. Using cleaning wipes to clean crew contacted surface also generates solid wastes. In this project, based on its success on high performance superhydrophobic and antimicrobial coatings, nGimat proposes to develop a novel cleaning technology, which can be applied onto a wide range of crew contacted surfaces and fabrics. The proposed effort by nGimat will create functional surfaces via CCVD so that surfactants are no longer needed to clean and much less solid wastes will be generated. In the meanwhile, the technology will also provide a cleaning pad to collect and hold the cleaning water/solution and dust for easy recycling and regeneration of cleaning water in microgravity environment, which will significantly reduce resource and energy usage and improve comfortableness and safety of the space habitats.

Next generation high-energy physics particle accelerators will require higher magnetic fields than current technology allows for, and Bismuth Strontium Calcium Copper Oxide (Bi2Sr2CaCu2O8, or Bi2212) superconductor is the leading candidate material to enable this advancement. In this effort, Bi2212 will be produced through a proprietary process that also successfully makes over 50 different oxide nanopowder products for commercial sale. The Phase IIA effort will advance Bi2212 powder product to the standards of quality and consistency required by end-user magnet manufacturers. In the SBIR Fast Track effort, Bi2212 powder that demonstrated competitive performance was developed. The Phase IIA effort will further advance the technical performance of Bi2212 powder as well as establish manufacturing practices that will enable consistent and reliable supply for the U.S. superconducting community. This will be achieved through new chemical formulations of the powder and implementing advanced manufacturing and quality-control protocols. The primary application for Bi2212 is in high-energy physics particle accelerators, but other commercial applications include high-field magnets used in Nuclear Magnetic Resonance spectrometers, Magnetic Resonance Imaging devices, and superconducting Fault Current Limiters. Given that commercialization of Bi2212 for particle accelerators is variable, alternative near-term commercial markets will also be investigated during and following the

Economical and efficient heat transfer technologies applicable to high-temperature, high-pressure conditions are a common requirement for advanced fossil energy and other thermal based power generation systems, in which heat is transferred from a heat source into a power cycle working fluid by means of heat exchange components. In addition to high temperature, these components experience high pressure or pressure fluctuations. Alloys with the required thermal and mechanical properties tend to be expensive but still have limited life due to corrosion. In contrast, many ceramic materials have high thermal stability and corrosion resistance that provide the potential to improve the system performance and durability. However, ceramics have low toughness and tension strength and require special engineering, especially for joining with metallic components. Therefore, novel technologies that enable joining ceramics with metals for high performance heat exchange components are urgently needed. With the goal of realizing high performance heat transfer components for modern power generation systems, nGimat Co. proposes the development of an enabling ceramic-metal joining technology based on the recently patented Flame Assisted Flashing Sintering (FAFS). This proprietary technology allows for one step process that enables densification and bonding of ceramic materials onto metal components. A novel ceramic-metal joining composition and structure via FAFS technology will be developed. Processing conditions such as flame temperature, applied field, scanning speed, and ceramic materials composition will be systematically studied to achieve optimal materials properties and bonding strength. Materials properties including ceramic/metal interface structure, hardness, and bonding strength will be tested according to industrial standards. With FAFS fabrication of high performance heat exchange components for power generation systems, nGimat will develop a novel ceramic-metal joining technology. FAFS can also benefit aerospace, nuclear, energy, and manufacturing industries by sintering/bonding ceramic thermal barrier layers onto turbine engine and combustor components. Commercial Applications and Other Benefits: The technology and materials developed will enable the fabrication of high performance heat exchange components for fossil energy power generation systems. FAFS can also be used to sintering/bonding ceramic thermal barrier layers onto turbine engine and combustor components, which can impact a variety of industries including aerospace, nuclear, energy, and manufacturing.
