Electrical insulation at cryogenic temperatures

The rapidly increasing activity in the field of cryogenics has established the need for a precise understanding of the physical and electrical behavior of insulating materials at the very low temperatures involved. Unlike the normal and higher temperature properties which are well-known, there is little background information and accumulated knowledge available to the design and application engineers. Consequently, it is necessary to start almost from scratch to study the electrical properties of insulating materials at cryogenic temperatures.
