Intermagnetics Achieves Key Milestone in Continuous Production of 2G HTS Tape


  • Longer Lengths, Higher Performance Expected

Latham, NY - Intermagnetics General Corporation (Nasdaq: IMGC) today announced IGC-SuperPower, LLC achieved a major milestone for calendar year 2001: continuous production of second-generation high-temperature superconducting (HTS) tapes. The second-generation tapes were produced in pilot-scale facilities established at Schenectady, N.Y., a year ago.

“Demonstration of continuous, versus batch, production of second-generation HTS material is a critical stepping stone in SuperPower’s goals of achieving longer lengths of high-performance second-generation HTS tapes and ultimately, routine, volume production of this high-performance material,” said Philip J. Pellegrino, Intermagnetics’ sector president – Energy Technology. “We remain on target to achieve our next objective of 100 amp-meter performance in greater than one-meter lengths during calendar 2002 and are now establishing a 2003 target of 1000 amp-meter performance in greater than 10 meter lengths. These targets are consistent with our previous projections to achieve commercial production of second-generation HTS by mid decade.”

Pellegrino noted the second-generation HTS tapes made using the continuous process achieved current density (current per unit cross-sectional area) in excess of one million amperes per square centimeter at liquid-nitrogen temperature. In comparison, a copper wire of the same cross-sectional area carries 1,000 to 10,000 times less current. SuperPower has been routinely producing 20-centimeter second-generation HTS tapes and recently produced the first meter-long tape.

Second-generation HTS conductor is produced using technologies similar to those used in semiconductor industries. Technical challenges in producing second-generation HTS conductor include using substrates of flexible metal tapes instead of rigid wafers and employing a process that could continue for days rather than a batch process that lasts a few hours. In meeting the milestone this year, SuperPower was able to demonstrate that second-generation technology can indeed be scaled to a continuous pilot-scale operation.

In addition to the dramatically less expensive materials employed in manufacturing second-generation HTS tape, the continuous production method should also reduce labor costs substantially compared with the process used in manufacturing first-generation HTS material. These are viewed as important developments in achieving the cost-benefit ratio that is critical to making HTS technology commercially viable.

SuperPower’s overall business objective is to develop commercial-level manufacturing processes for HTS material and devices that will increase the capacity, reliability and quality of transmission and distribution of electric power.

SuperPower was granted an exclusive license for second-generation HTS process technology from Los Alamos National Lab last year and developed additional technology exclusively with Los Alamos over the past year. The second-generation HTS tapes produced by Los Alamos still hold the world-record for the best performance.
