An Investigation Over Superconductive Inductive and Capacitive Components for High-Precision Measurements

Superconducting inductive and capacitive components seem to be very appealing for many high-precision measurements because of their reduced dissipation. Some tests made at Istituto Nazionale di Ricerca Metrologica have proved the possibility of building inductors with quality factor higher than several thousand in the acoustic frequency band using copper clad Nb-Ti wires. However, the best performances have been obtained with pure Nb wire, in spite of some connection problems.
