Abstract
A superconducting current measuring circuit is provided with a detection loop through which a current flows by the influence of a magnetic field generated by a measurement target current. The detection loop contains a superconductor. The superconducting current measuring circuit is also provided with a superconducting sampler circuit for measuring the current flowing through the detection loop.
Claims2
A superconducting current measuring circuit comprising:
- a detection loop through which a shield current flows by influence of a magnetic field generated by a measurement target current, said detection loop containing a superconductor;
- a superconducting sampler circuit measuring said shield current;
- and
- a magnetic field collector which collects said magnetic field generated by said measurement target current, wherein said magnetic field collector comprises a probe containing a soft magnetic material, said probe being arranged such that a tip end thereof faces a measurement target through which said measurement target current flows and another end penetrates into said detection loop.
