TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
For Adiabatic Demagnetization Refrigerators (ADRs) in space applications, it is desirable to have very light weight, small diameter, high current density superconducting wires that can operate at temperatures in the 10-30 K range, specifically with engineering current densities in the 50,000-100,000 A/cm2 range, at 15K in 3 tesla fields. Magnesium diboride, a light-weight superconductor wire, is the ideal candidate coil material for ADRs in the 10-30 K range. During the Phase I we demonstrated that drawing magnesium diboride wires to the needed diameter range could be achieved. However to meet the most desired application requirements we need slight improvement in superconductor current density, reduction of powder filament size, and higher percent superconductor fraction at the desired wire diameter range of 0.075 mm - 0.150 mm. In the Phase II effort we propose a development plan to make these improvements to small diameter magnesium diboride wire and to demonstrate conductor performance over long length on small coils.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
In addition to ADR coils, magnesium diboride superconductors can benefit NASA applications for superconducting large aircraft motors, transformers, inductors, magnetic bearings, actuators, MHD magnets, and other potential power conditioning applications.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Commercialization of magnesium diboride superconducting wires will allow less expensive and more open MRI systems for medical use, and lower cost and more efficient power utility applications such as transformers, motors, generators, fault current limiters, and SMES. Magnesium diboride will also be useful for superconducting Maglev Trains for the transportation industry, and for the High Energy Physics community the magnesium diboride wire will be useful for wiggler and undulator magnets.
