Small Business Innovation Research
INNOVATION Miniature, high
speed vibration free, turboalternator

• ACCOMPLISHMENTS
• High speed shaft in cryogenic gas bearings.
• High precision, automated miniature rotor
  fabrication techniques.
• Demonstrated shaft/bearing system at 50o Kelvin.
• Achieved design speed and power targets for the
  alternator.
• COMMERCIALIZATION
• Longer term commercial applications include
  cryocoolers for low temperature and high
  temperature superconducting medical and
  electronics instruments.

• GOVERNMENT/SCIENCE APPLICATIONS
• A 13 million multi-year Phase III contract
  awarded by NASA resulted in the successful
  installation and operation of a 75K cooler on
  Hubble Space Telescope NICMOS instrument.
• Multi-stage coolers for Air Force space IR
  sensors at temperatures as low as 10K.
• Likely bidder for a 4oK to 6oK cooler for James
  Webb Space Telescope MIRI instrument.
