ABSTRACT:
A dilution refrigerator, the combination comprising an electrostatic mixing chamber containing .sup.3 He-rich and .sup.4 He-rich phases subject to separation in response to electrostatic force application, the chamber having an outlet for .sup.3 He that has passed through an interface between those two liquid phases to produce cooling; a still connected with the mixing chamber to receive .sup.3 He therefrom, the still having an outlet for .sup.3 He; two adsorption pumps connected with said still outlet to receive .sup.3 He vapor, alternately, there being a valve or valve system connected with each pump; heater structure associated with the pumps to cause .sup.3 He desorption by the pumps; a condenser-collector connected with the valves to receive desorbed .sup.3 He, .sup.3 He liquid being held at a flow path outlet from the condenser-collector; and a heat exchanger connected in a flow path from the condenser-collector back to the mixing chamber.
