Abstract

The invention provides a sample cell, and the sample cell provides for holding a sample to be placed in the cryogenic cooling environment. The sample cell comprises an airtight, openable and closable housing (101). A sample base (102) for receiving a sample is within the housing. A refrigeration accessory (103) is provided for attaching the sample cell to a refrigeration body of a cryogenic cooling environment. The sample cell includes a thermal connection (104) between the sample base (102) and the refrigeration accessory (103). One or more hermetic connectors (105) are provided for establishing an electrical connection between the interior and exterior of the housing (101).

Description

technical field

[0001] In general, the present invention relates to sample processing techniques at room temperature and cryogenic environments. In particular, the present invention relates to the protection of samples from detrimental effects of environmental conditions when the samples are not subjected to active measurements in cryogenic environments. Background technique

[0002] Many applications require the cooling of relatively small pieces of material, often called samples, to very low temperatures during various measurements and manipulations. Examples of such samples include, but are not limited to, quantum circuit elements used in quantum computing. Other examples are, for example, pieces of complex materials such as graphene, other atomically thin-film materials, carbon nanotubes and fullerenes, among others. Here, cryogenic refers to temperatures that can only be achieved in cryogenic cooling systems: temperatures below 10K, often below 4K, and in many cases o...
