II.2.4)Description of the procurement:

In the Hensen group at Leiden University we aim to achieve ultralow vibrations at ultralow temperatures in a cryogen free dilution refrigerator for the study of the interaction between quantum mechanics and gravity using an on-chip levitation platform. This research requires a specialized cryostat system, with the following properties:

To keep operational costs low we need the dilution refrigerator to be cooled with a closed cycle pulse tube system.

The ultralow vibrations, in combination with a closed cycle cryostat require specialized modifications to the cryostat system. In particular, parts of the cryostat that are normally rigidly fixed need to be loosely suspended, to avoid vibrations from entering the experimental space at the bottom of the cryostat.

In order to reach sufficiently low temperatures, below the standard dilution refrigerator temperature of around 10 mK, a PrNi5 nuclear demagnetization stage is required.

Because of the system’s size and complexity it is crucial to allow a for fast sample exchange mechanism that operates when the fridge is already cold. Such a cold-insertable probe allows for fast testing and prototyping of fabricated chips.
