A superconducting quantum-interference flux-meter

Creators

Description

The flux meter is based on the SQUID-effect to give a cyclic answer from the magnetic flux, which is incremented in steps of one flux quantum. The system can be used at all temperatures, as amplitude and frequency of the ac-current of the SQUID and the phase difference between the exciting ac-currents are controlled by the multi-frequency exciting ac-current power system. For this purpose electromagnetic coupling with ac-currents of several frequencies is used. (DG)

Abstract (German)

Der Flussmesser nutzt das Merkmal des SQUID aus, um zyklische Antworten auf den Magnetfluss durch Inkremente oder Schritte von jeweils einem Flussquant zu erteilen. Er ist bei jeder Temperatur einsetzbar, da Amplitude und Frequenz des an das SQUID angelegten Wechselstromes und die Phasendifferenz zwischen der Anzahl von Erreger-Wechselstroemen im Multifrequenz-Erreger-Wechselstrom-Beaufschlagungssystem gesteuert werden. Hierzu dient eine elektromagnetische Kupplung mit erregendem Wechselstrom mit mehreren Frequenzkomponenten. (DG)
