Abstract
A sample cell is provided for holding a sample to be placed in a cryogenically cooled environment. The sample cell comprises an airtight, openable and closable enclosure. Within said enclosure is a sample base for receiving the sample. A refrigerator attachment is provided for attaching the sample cell to a refrigerated body of a cryogenically cooled environment. The sample cell comprises a thermal connection between the sample base and the refrigerator attachment. One or more air-tight connectors are provided for establishing electric connections between inside and outside of said enclosure.
