Abstract
A detailed calculation of the sensitivity of a cryogenic current comparator (CCC) has been completed. The model accounts for the current distribution on the closed external shield and the overlapped shield around the windings. Additional refinements to the model lead to excellent agreement with sensitivity measurements for a range of CCC geometries.
