AMERICAN SUPERCONDUCTOR DEMONSTRATES WORLD'S FIRST FULLY INTEGRATED HTS SYSTEM

 Prototype Development Two Years Ahead of Navy Projections
 ALBUQUERQUE, N.M., July 15 /PRNewswire/ -- American Superconductor Corporation (NASDAQ: AMSC) today announced the successful testing of the world's first fully integrated device using high temperature superconducting (HTS) coils. The prototype product, developed by AMSC in collaboration with the Naval Undersea Warfare Center (NUWC), was designed specifically for sonar applications.
 A model of the prototype product is being shown at the International Cryogenics and Materials Conference this week in Albuquerque, where the scientific and engineering community is presenting results in the field of very low temperature materials and applications.
 The device, known as an acoustic transducer, converts electric power into acoustic power with high efficiency. It answers a major need the U.S. Navy has identified for superior sonar capabilities in shallow ocean water locations, e.g., beaches, shallow seas (i.e., the Persian Gulf) to maximize security of U.S. defense forces. The superconducting sonar device enables more sophisticated signal processing and, in return, "signature recognition" -- the ability to identify objects by means of distinctive sonar echoes.
 According to data being reported at the conference, AMSC and NUWC were able to successfully test the system in water at depths up to 100 feet. The development of the device is two years ahead of the Navy's expectations, according to AMSC.
 "The delivery of a fully integrated HTS system -- one which combines superconducting coils with the cryogenic refrigeration and electronics required to operate the system -- demonstrates the progress made in providing the benefits of HTS technology in a commercially viable form," explained Gregory J. Yurek, American Superconductor Corporation's president and CEO. He also pointed out that this prototype product, which requires the use of alternating current (AC) in the HTS coils, demonstrates that HTS materials are very suitable for AC applications including power cables, motors, and many others.
 The U.S. Navy is striving to develop lightweight, high-energy- density acoustic sources, and emergence of this technology is expected to be of tremendous benefit to its efforts. The transducer's many applications include undersea surveillance, ocean mapping, and oil exploration.
 The cryogenic refrigerator incorporated in the device was supplied by Carrier Corporation. This refrigerator, known as a Stirling-cycle cryocooler, keeps the HTS coils in the device at 50-70 degrees Kelvin (-410 to -390 degrees F), well below the temperature required for them to be fully superconducting. No liquid coolants are required.
 The device also incorporates an advanced magnetostrictive material, which provides the means for converting electric power into acoustic power. Magnetostrictive materials change length when exposed to a changing magnetic field. The combination of HTS coils, which create the magnetic field, with an advanced magnetostrictive material yields acoustic performance in a range of power and frequency that was never before accessible.
 The design, fabrication, and testing of the device was funded by the Navy's Small Business Innovation Research (SBIR) program and the Office of Naval Research.
 The Naval Undersea Warfare Center's mission is to provide research, development, test and evaluation for submarines, autonomous underwater undersea offensive and defensive weapon systems associated with undersea warfare.
 Amercan Superconductor Corporation creates and develops materials and manufacturing processes for making flexible high temperature ceramic superconducting wires and wire products. The Company, based in Westborough, Massachusetts, is dedicated to the development and manufacture of commercially viable sperconducting systems.
