✦ Synopsis

A 3He/4He dilution refrigerator is described where the instreaming 3He is precooled and liquefied by a counterflow heat exchanger which makes use of the enthalpy of the cold 3He gas pumped out of the still, and by subsequent Joule-Thomson expansion. This condenser replaces the usual 4He condenser.

This condensation stage has the great advantage, that the dilution refrigerator can work without a separate 1 K stage (for example, a cold plate or a pumped He 4 bath). This one dispenses with a pumping line and a rotary pump. This stage is ideally suited for runs of long duration.

The sensitivity increase in bolometers obtained by operating temperatures of 1 K (helium-4) and 0.3 K (helium-3), with respect to standard bolometers cooled at pumped 4He temperature, represents in infrared and submillimetric astronomy a remarkable step forward in applications both on large ground t
