Description

For the future spaceport and long-term storage of liquid hydrogen NASA requires cryocoolers that can provide cooling power in the range of 20 watts at 20 K. The closed-cycle cooling alternatives currently available for such applications are not well suited to the requirements. In many cases reliability is low and vibration high. In other cases coolers are too massive and inefficient. This proposal describes a two-stage pulse tube cryocooler that combines several innovative design features. The proposed pulse tube will be light-weight, efficient, reliable, vibration free, and easy to integrate with cryogenic dewars.
