Industrial exploitation of a novel, miniature dilution refrigerator and associated vibrometry

Lead Research Organisation: University of Manchester
Department Name: Physics and Astronomy

Abstract

Extremely low temperatures (below 100 mK) are used in many fields, from cooling detectors for Astronomy research, to solid state physics, plasma physics and quantum computing research. In the last decade, mechanical coolers (Pulse Tube Coolers mainly) are being offered commercially with low vibrations with the potential of making cryogenic systems so called "dry", i.e. without the use of any cryogenic liquid like liquid helium and/or liquid nitrogen. There is a market for these "dry" systems capable of reaching below 100 mK - mostly using dilution refrigerators. It is therefore important to provide researchers and industries with simple commercial systems that are cryogen free, low vibration, no external re-circulation pumps, all completely electrically operated without cold moving parts. Based on our experience in building prototypes of dilution refrigerators for astronomical instruments, we now propose to bring to the market such a system. To make such systems particularly interesting, we also propose to set-up a cryogenic vibrometry facility to certify accurately the level of vibrations of the commercial systems.

Description We have now a robust design for a commercial grade sub-K refrigerator and novel sensors for cryogenic vibrometry.
Exploitation Route Several systems in need of versatile cryo free sub-K system will find our cryogenics extremely well suited. Examples are in the field of chemistry (dry sub-K EPR systems), astronomy and security (dry sub-K mm and sub-mm detector systems), etc.
