Cryogen-free 3U/4U mixed cooler for generating low temperatures down to below 10 mK with large sample volumes and for investigating solid-state quantum systems (see service description for details)

A cryogen-free 3U/4U mixed cooler is procured to generate low temperatures down to below 10mK. The mixing cooler must allow the investigation and control of solid-state quantum systems. For this purpose, the mixing cooler must have the technical specifications that enable the experimental investigation of such systems. For this purpose, the mixing cooler must in particular have a sufficiently large sample volume to accommodate the experiments, a sufficiently high cooling capacity, and a large number of microwave lines. The desired technical specifications and the exclusion criteria are listed in the service description.
