An apparatus for measuring the specific heat of solids from 2 to 300 K is described. The equipment uses two cells, one of which contains the sample, the other being equal in mass to the addenda around the sample. They are surrounded by a screen; the temperature of which is raised at a constant rate.

T HE specific heat of a non-superconducting metal or alloy can usually be represented, at sufficiently low temperatures, by an expression of the form C = ?T + fiT 3 . . .
A non mechanical gas sorption refrigeration system which could be powered by a low temperature heat source was designed and analysed. The system involved no sealing, no mechanical moving parts and no active control The system was analysed using a 1 W cooling load at 74 K as an example. It was found
Two types of heat sinks for cryogenic applications have been made with commercial technology. Both are described and analysed.
