The small regenerative cryocooler is regarded as an instrument for cryorefrigeration whose instrument constant is designated as Cj (j=A, B, C). The cooler is represented by a reversible Carnot refrigerator–irreversible link combination. The refrige

Small Nb/Ti-Cu prototype superconducting coils have been wound using LBL-supplied wire, which has been normally applied to Rutherford cabled dipoles. The studies are being conducted in the context of planning versions of toroidal winding systems for

In the context of developing heuristic rules for troubleshooting a cryogenic liquefier using an expert system, effects of heat leak location on performance are presented. Though heat leaks into the cryosystem from the surroundings are undesirable, th

The electrical contact resistance of stainless steel screen stacks at room temperature and at liquid nitrogen temperature has been measured as a function of externally applied mechanical load (weight). The data show a nearly linear voltage versus cur
