Title Sionludi XL

Tabletop

The Sionludi is a compact tabletop closed-cycle dilution refrigerator with milli-Kelvin base temperature. The term tabletop is meant to be understood literally. Its unconventional layout enables a direct installation of the cryostat on a simple table. This makes the everyday operation very convenient and reduces the space requirement for the cryostat.

High Modularity

The cryostat exhibits a modular design which enables the installation of different components such as low frequency and RF wiring, passive RF devices, optical fibers and more. Three removable access ports at each temperature stage and twelve demountable windows at the vacuum shield allow a simple exchange of experimental equipment.

Low Vibrations

Vibrations are usually an undesired source of troubles. The small height, heavy mass, and stiff support structure of the cryostat makes it very insusceptible to vibrations. Unavoidable sources of vibrations such as vacuum and circulation pumps are mechanically decoupled from the cryostat.

Turnkey Operation

The complete cooldown, warm-up and intermediate states are automatized one-button operations. General control of the cryostat is enabled by an elaborated platform-independent web interface. The interface also provides the ability to adjust the operation on the interactive user interface as well as write and read parameters with external ethernet interfaces such as Python or MATLAB.

Vast Experimental Space

Despite its compact size, the Sionludi XL offers a large experimental volume at base temperature. The default experimental volume has a diameter of 295mm and a height of 300mm. If necessary, its upside-down design allows a straightforward increase of the experimental volume height. A more compact and economical version is its little brother, the Sionludi L.
