A new ultra-low-temperature cryogen-free experimental platform

Abstract

We report the introduction of a new cryogen-free dilution refrigerator experimental platform that provides significant performance enhancements, in several key areas, over the current generation of systems. In particular the ability to: install more experimental services; install higher-field experimental magnets; dissipate more power at the ∼ 4 K stage; and to attain higher cooling powers and lower base-temperatures (below 3.5 mK) at the mixing chamber plate.
