Efficient vibration isolation for a cryogen-free dilution refrigerator

Quantum experiments and technologies often require temperatures as low as one-hundredth of a degree above absolute zero. “Cryogen-free dilution refrigerators” are advanced instruments to reach and maintain such temperatures simply and economically. However, they come with the price of significant vibrations – mechanical noise that can be detrimental for many applications. The low-temperature community explored different approaches to mitigate vibrations, but these solutions were usually highly specialized, not economical, and never left the research lab of universities. This project aims at developing a comprehensive, efficient, and economical solution for the broad market of cryogen-free dilution refrigerators. For this purpose, we will also implement and characterize novel vibration isolation systems – including one that is already operating for a superfluid dark matter detector at the University of Alberta.
