Abstract
The Advanced Technology Center of Lockheed Martin is developing high-capacity (10 W @ 77 K) and low-capacity (0.5 W @ 77 K) pulse tube cryocoolers as part of a program to develop reduced weight satellite communications payloads utilizing high-temperature superconducting (HTS) microwave circuits. A consortium of Com Dev, DuPont, and Lockheed Martin is working together with NASA Lewis Research Center to develop this technology under a DARPA program.
The cooling performance and system characteristics of both the high-power and low power cryocooler systems are described in this paper.
