Abstract

A custom-designed laboratory prototype of a four-stage Stirling-type pulse tube cryocooler was recently developed by Lockheed Martin for niobium integrated circuits (ICs) operating close to 4 K. Basic system performance has been verified by integration with a Nb IC test chip, with cells that include a high-speed rapid single flux quantum (RSFQ) binary counter. For 650 W total compressor power, extended stable operation of the counter at T=4.5 K was demonstrated with a clock frequency up to 46 GHz, with 25 mW of excess cooling capacity on the coldest stage. The thermodynamic, electromagnetic, and mechanical performance are promising for the development of an improved compact cryocooler for practical superconducting electronic applications in fields such as wireless communications.
