Cryogenic Technologies Project


The mission of the Cryogenic Technologies Project at NIST is to conduct research in cryogenics, working with industry and other government agencies in the development of new and/or improved processes and products involving cryogenic technologies.

To read an encyclopedic article providing information about cryogenics follow this link.

Major Program Elements

  • Develop advanced measurement techniques and standard measurements practices for cryogenic processes.
  • Investigate new and innovative cryogenic refrigeration processes.
  • Develop mathematical models for cryogenic processes.
  • Design and test prototype components and systems to compare performance with models to improve modeling techniques.
  • Provide critically evaluated data for the properties of solid materials at cryogenic temperature.
  • Assist in development of bibliographic database on cryogenics.
  • Conduct calibrations of cryogenic flow meters.

Cryogenic Flow Facility

The Division operates the NIST Cryogenic Flow Measurement Facility, located in Boulder, Colorado.  Please follow the link to learn more about this world-class testing facility.


Properties data for materials from ambient to cryogenic temperature (300 to 4 K) is available by clicking here.

Microcryocooler for Terahertz Detectors— NIST and the University of Colorado have been funded since April, 2006, by DARPA to develop a microcryocooler with a volume less than about 4 cm3 to cool a terahertz detector to about 77 K. The …

Low Temperature Regenerator and Pulse Tube Losses—The Cryogenic Technologies Project has been funded by ONR since FY2005 to measure and model the losses in 4 K regenerators and pulse tubes. These thermal components are part of 4 K cryocoolers to …


Picture of Ray Radebaugh and the Samuel C. Collins award








Dr. Ray Radebaugh receives Samuel C. Collins Award. At the CEC/ICMC Awards Breakfast on July 2, Ray Radebaugh received the prestigious Samuel C. Collins Award for “an individual who has made outstanding contributions to the identification and solution of cryogenic engineering problems and has…demonstrated a concern for the cryogenic community through unselfish professional service and leadership to this community.” Radebaugh recently retired from NIST, but is continuing in a consulting role with the institute.
