Abstract

We have designed, constructed, and tested an electrical vacuum feedthrough that can carry a large number of microwave signal lines, has high vacuum compatibility, and is highly customizable. We found that it had a leak rate of approximately 10^(-7) Pa*L/s (7.5x10^(-9) torr*L/s), making it suitable for high-vacuum systems such as cryostats. The feedthrough is low-cost, and the PCB-based design allows the choice of any surface-mountable microwave connector. We additionally verified operation through consistent use on a real cryogenic system and verified the mechanical robustness of the feedthrough.
