In the past, temperatures below -100°C have been produced primarily via the liquefaction of gases with a low boiling point. Recently the available arsenal of liquefaction apparatus has been augmented by the introduction by the Philips Company of the “gas refrigerating machine” employing the Stirling cycle, in its first version of an air liquefier [1].
