摘要:

A simple device is described for rapidly cycling apparatus between 300 and ∼1 K within a helium storage Dewar. The arrangement is useful for testing components or conducting experiments over this temperature range when the apparatus to be cooled is less than 5 cm in diameter and 50 cm long. Helium evaporation on inserting the device is ∼0.2 l, with consumption ∼0.1 l/h during operation.
