Abstract

Analytical expressions to calculate the geometrical characteristics of ac high-voltage high-current cryogenic current leads have been presented. An algorithm to calculate the temperature dependence of specific resistance and thermal conductivity coefficient of technical copper at low temperatures depending on the metal purity has been developed and described.
