mal imaging systems. DOD has established a family of SADAs to address high performance (SADA I), mid-to-high performance (SADA II), and compact class (SADA III) systems. SADAs consist of the Infrared Focal Plane Array (IRFPA), Dewar, Command & Control Electronics (C&CE), and the cryogenic coolers. S

These flexures have been shown to provide smoother, lower vibration piston motion than previously obtained with conventional three finger spiral flexures. Acceptance Tests validated the required perfor

The Importance of Being Upside-Downur analysis shows that hybrids consisting of a Joule-Thomson (J-T) cooler coupled with a mechanical cooler are the most efficient when used in a low Earth orbit. We are developing a hybrid cryocooler consisting of a helium J-T system coupled to a Stirling cycle mechanical cooler for these applicatio

Awakening Mindfulness in Science Educationproperties associated with geometry, materials, gas properties, heat transfer devices, flow manifolds, mechanical mechanisms, and electro-mechanical devices that determine a particular machine’s performance make quick optimization difficult. Single-stage coolers are now sufficiently well understood

The price of the cryocooler is projected to be $2,000 per unit in lots of 10,000, with availability in the first quarter of 2001. In comparison to the M77 cryocooler, the M87 shows enhanced rated efficiency (20%), improved cooling power, a
