  • Secondary pulse tubes and regenerators for coupling to room temperature phase shifters in multistage pulse tube cryocoolers
    Patent number: 8950193
    Abstract: Pulse tube refrigeration or cooling systems are described which utilize a secondary regenerator or a secondary pulse tube. Use of such a secondary regenerator or pulse tube enables a commercially available pressure oscillator to be incorporated in the cooling system. The commercially available oscillator can be operated at room temperature or approximately so.
    Type: Grant
    Filed: January 24, 2011
    Date of Patent: February 10, 2015
    Assignee: The United States of America, as Represented by the Secretary of Commerce, the National Institute of Standards and Technology
    Inventors: Ray Radebaugh, Isaac Garaway, Peter E. Bradley
