abstract
A large desorption cryostat particularly suited for measurement of the properties of cryogenic materials between 1.5 and 60K is described. In the difficult range above 20K temperature control and uniformity remains excellent. For measurements above 20K either hydrogen or helium may be used as the adsorptive. The temperature range of the cryostat may be extended to 120K with the use of nitrogen as the adsorptive. 1973 The American Institute of Physics.
