The characteristics and performance of an improved 3He/4He double stage refrigerator are presented. It is based on the same principle as the previous double stage refrigerator described in reference 1. A new geometry was used to overcome both the extra thermal input due to gas convection in the cond

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
A refrigerator capable of operating both in evaporation and dilution modes is described. The refrigerator provides preliminary cooling of investigated samples down to a starting temperature of about 0.3 K and permits the location of samples directly in the mixing chamber as well as their replacement
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.
