PULSE TUBE CRYOCOOLERS: A CRYOGEN-FREE PATH TO 2K.
AIM develops and manufactures state of the art Stirling and Pulse-Tube cryocoolers for infrared and high-temperature superconducting applications. The system utilizes a recently developed two-stage 4K pulse-tube refrigerator developed by Dr. Chao Wang of Cryomech, Incorporated, Syracuse, New York. A classical example of cryocooler modeling is that of the Stirling Cooler. One advantage of a pulse tube cryocooler over a GM cryocooler is that the pulse tube cryocooler-Technical Data-21chemnet. Other Cooling Technologies; Competitive Comparison; How does it all work? Janis Research offers single-stage and two-stage pulse tube cryocoolers, 4 Kelvin closed cycle refrigerators and vibrtaion isolation systems. Other companies have expressed interest in this market, and both mixed-gas J-T and pulse tube cryocoolers have been discussed as oxygen liquefiers. Our acoustic Stirling (pulse-tube) cryocooler line includes the industry's widest capacity range of unitary coolers. Having no moving parts in the cold, the pulse tube cold finger has a very low vibration and magnetic noise. Since 1998, 12 of the 13 U.S.-manufactured long-life pulse tube or Stirling cryocoolers in space have been built by Northrop Grumman.
