Abstract
The calculation of inductances of superconducting structures like the cryogenic current comparator (CCC) is not straightforward due to image effects and unknown current distributions. By treating the problem as a magnetic circuit, an approximate analytical expression for the self-inductance of the shielded CCC is obtained. This formula can be used to derive a "rule of thumb" for maximizing the value of an inductance inside a superconducting shield. Using this rule the design of an optimum CCC is simplified.
