The application of moderately high pressures to work at low temperatures is described. The problems involved in the merging of these two disciplines are discussed as they relate to laboratory research as well as to large scale nuclear rocket testing facility usage. The equipment used to determine some physical properties of liquid cryogens up to 50000 lb/in./sup 2/ are also described. The methods of obtaining and applying the low temperature to the high pressure volume will be mentioned. The use of a reciprocating piston pump to pump cryogenic liquids to high pressures is described. Consideration is also given to the problems of cryogenic seals for large size vacuum jacketed cryogenic piping. Safety requirements are also mentioned. (P.C.H.
