Dependence of SQUID dynamics on excitation signal shape and type of detection

Abstract

The influence of the shape of voltage signals (excitation and raference) in a RF souio magnetometer, on t h e dynamics of the approach to the stationary state, in response to a jump of magnetic flux, is analysed. The reduced time required for reaching a particular final accuracy has been determined. The best combinations of signal forms, excitation and reference, capable of shortening the settling time without degradation of t h e accuracy have been found.
