Abstract: A variable temperature dewar in which a heat load is thermally connected to a heat sink by a short heat pipe, the temperature of the load being varied by varying the pressure in the heat pipe to vary the boiling temperature of a cryogenic fluid contained therein, of which the liquid phase is in conductive thermal contact with the load and the gas phase is in conductive thermal contact with the sink.
