Abstract
A cryogenic current comparator is being developed at NML to give high accuracy comparisons of room temperature resistors and quantized Hall resistances. The comparator incorporates novel developments in the method of calibrating auxiliary currents and in the method of construction of the superconducting shielding around the comparator windings.<>
