Abstract
A new type of coaxial shunts, with nominal current from 20 mA to 20 A have been designed at I.N.RI.M.. Different approaches have been used to built them, depending on their nominal current. In the currents between 100 mA and 20 A they are made as a disk structure, using either SMD resistors or manganin foils. In order to reduce stray effects, their structures have ideally no common magnetic interaction between the input current and the output voltage, allowing a flat response in a wide frequency range.
