Particle size distribution is one of the critical parameters in fabricating high-performance, fine-filament superconductors of Nb3Sn and Bi-2212 using the powder-in-tube (PIT) technique. Even a few large particles in the tubes of a multi-filament PIT billet will limit the size of the drawing or rolling to finish dimension. Since performance scales with the number of filaments in a strand, improv ...

70576 The Nb3Sn superconductor is an enabling technology that will determine the future of high-energy hadron colliders for high energy physics research. Unfortunately, the cost of the Nb3Sn superconductor is ten times that of other superconductors. The high cost comes not from materials, but from the necessity to fabricate the multi-filament wire in small batches. Batch size is limited by ...

65438 Large particles must be efficiently removed from powders used to fabricate superconducting wire. The presence of even a trace amount of large particles can ruin the superconducting properties of a large batch of wire, and limit the performance of all wire made with the powder-in-tube process. This project will apply an aerosol sorting technology to remove this limitation to supercon ...

65507 Adhesive systems are needed for the assembly of detectors for high-energy physics applications, especially an adhesive that cures upon the application of an external stimulation, such as UV light. However, the end use of these detectors requires extensive shielding to protect the detectors from impinging stray light that might interfere with the small responses generated during subsequent ...

65544 Nuclear physics research requires large detectors that can detect particles with good spatial and time resolution. However, these devices are expensive to build and require high maintenance. They also require a large solid support structure, which adds to overall project cost. This project will integrate a new scintillator material into a fiber-optic-based array to produce a high-resolut ...

65437 In closed waste-storage systems containing either easily oxidizable metals or radioactive materials, molecular hydrogen is produced. If these closed containers have hydrogen impermeable shells or cases, the build-up of hydrogen gas may form an explosive or flammable mixture with any contained air. It may also present a corrosion problem for certain reactive metal elements that tend to for ...

65532 The recycling of mixed or contaminated plastic could save energy. However, the products of most recycling processes used today are of low quality and represent only a shifting of the problem by one product generation. This project will adapt an existing technology for the recycling of polystyrene waste from food service operations with the recovery of monomers and other valuable raw mater ...

The recycling of thermoset composite materials produces valuable fibers and a liquid hydrocarbon byproduct. The liquid hydrocarbons constitute a potential hazardous wastestream that could prevent the recycling process from being adopted on a large scale by government and industrial users. This project addresses the conversion of these liquid hydrocarbons into useful products. Phase I showed tha ...
