Abstract

PURPOSE: To realize the cost reduction of a measuring element and high-sensitivity detection of magnetic field intensity under an cryogenic temperature by detecting normal conduction transfer by providing a superconductor with a search coil which can heat the superconductor with power ON.
CONSTITUTION: At the center part of superconductor 1 coated with copper 2, search coil 4 is wound and they are sealed and fixed by adibatic agent 6 together with lead wires 3 and 5 to constitute measuring element 7, which is installed in low- temperature container 8. To lead wire 3, a constant current supply is connecte and to lead wire 5, variable voltage power supply 12 and normal conduction transfer detector 10 are both connected. In this constitution, a current through search coil 4 is increased with a current through superconductor 1 constant to reduce the critical magnetic field of superconductor 1, so that superconductor 1 will change into a normal conductor being applied with a slight magnetic field. For the purpose, unknown magnetic field intensity can be detected from the current value of search coil 4 by previously knowing the relation between the both.
