Holder for a sample to be cooled to a low temperature in a vacuum space and ³He—⁴He dilution refrigerator adapted to accommodate such a holder

摘要

Holder (1) for a sample to be cooled to a low temperature in a vacuum space, comprising a carrier body (2) for carrying the sample in thermal contact and contact means (3, 4, 5) for bringing the carrier body into thermal contact with a cooling body to be brought to the low temperature, wherein the contact means can be switched between a first mode, in which there is no thermal contact between the carrier body and the cooling body, and a second mode in which there is thermal contact between the carrier body and the cooling body, and a probe for inserting into a vacuum space in a refrigerator such a holder for a sample to be cooled to a low temperature in this vacuum space, and a refrigerator, in particular a 3He-4He dilution refrigerator, adapted to accommodate such a probe.
