QUANTUM INTERFERENCE TYPE FLUXMETER PRODUCTION METHOD

摘要

A quantum interference type fluxmeter production method comprising a step of forming a pickup coil portion as a unitary block with an input coil by migration electrodeposition and sintering of high-temperature superconductive fine particles onto an outer surface of a first cylindrical ceramic substrate. Method also comprises a step of forming a high-temperature superconductive magnetic shield pipe by migration electrodeposition and sintering of high-temperature superconductive fine particles onto an entire outer surface of a second cylindrical ceramic substrate, and a step of magnetically connecting the input coil to a high-temperature superconductive quantum interference type element by arranging the pickup coil portion in such a manner that its tip end is inserted into the lower end portion of the magnetic shield pipe and by inserting the high-temperature superconductive quantum interference type element into the upper end of the magnetic shield pipe.
