We will develop porous silicon based detector chips for the identification of biomoleculefragments. Patches of porous silicon on a silicon wafer act as active sieves, loaded with taggingmolecules, where during passage through it biomolecule fragments are identified by their response afterattachment… More

Accelerator Technology Corp. proposes to develop a compact, cost-effective elctron-beam disinfestation system for pasteurization of meat patties. The system is designed to be integrated into the production line of a conventional meat patty operation. In such operations, the patties are stamped… More

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… More

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… More

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… More

73043S03-I The cladding of fuel rods for Gen IV nuclear reactors must operate under extremely harsh conditions: high temperature (up to 1000 C in some designs), radiation damage from both fast and thermal neutrons, and attack by corrosive liquids (sodium and lead in some designs). The properties… More

73042S03-I Nb3Sn superconductor is a key enabling technology that will determine the feasibility of high-energy hadron colliders for high energy physics research. However, the cost of Nb3Sn superconductor is ten times higher than that of other superconductors. The high cost comes not from… More

78953 In the fabrication of powder-in-tube (PIT) Nb3Sn superconductors, needed for high energy physics applications, the particle size distribution limits the final filament size to which the strand can be drawn. In previous work, a virtual impactor (VI) aerosol particle sizing process was… More

The removal of all particles over a desired micron-scale size threshold from a powder sample is critical to the development of fine-filament, powder-in-tube superconducting wires, for which the final filament size is limited by the largest particles in the precursor powder filling. This project… More

MgB2 is proving to be a very promising superconductor. Until recently, the low critical field of pure MgB2 had inhibited its use for higher-field applications, such as for high energy physics experiments. Yet, recent advances have demonstrated a dramatic enhancement of the upper critical field… More

Superconducting wire is used in electromagnets that are used in energy research particle accelerators, fusion tokomaks and in biomedical research - NMR imaging and spectroscopy. New frontiers in those areas of research require ever higher magnetic field strength, and that requires ever-more robust… More
