Our institute - the Institute of Solid State Physics - is situated in the Freihaus Building of TU Wien right in the center of Vienna. For the Dry Dilution Refrigerator, we chose a low-vibration room on the 4th underground floor that we can design and tailor to meet our needs. Here, we have access to cooling water, HV electricity, and materials for vibration and noise damping. The room has a high ceiling and a crane just above the cryostat, which we can operate from the floor or balcony level.

Five gold-plated circular copper plates attached to one another with glass fiber rods. Every plate has a different temperature. The bottom one is the mixing chamber plate with the lowest temperature of 5mK.

The system consists of five gold-plated circular copper plates attached to one another with glass fiber rods. Every plate has a different temperature. The bottom one is the mixing chamber plate with the lowest temperature of 5 mK.
We use top loading probes for fast sample exchange from 300K to base temperature. The smaller probe can be mounted in the center of the plate or sidewise in one of the ports. The bigger probe is mounted in the central port.
