APPARATUS OF CONNECTING PICKUP COIL TO SQUID LOOP OF SERIALLY COUPLED SQUID SENSOR, ESPECIALLY UTILIZING A SUPERCONDUCTING WIRE

摘要

PURPOSE: An apparatus of connecting a pickup coil to a squid loop of a serially coupled squid sensor is provided to maintain an interval for effectively removing interference of magnetic field between the pickup coil and the squid loop by using a superconducting wire. CONSTITUTION: A serially coupled squid sensor includes a pickup coil(10) having large inductance, a squid loop(20) having small inductance, and a superconducting wire(30) formed between the pickup coil and the squid loop. An area of the superconducting wire connected to the pickup coil is smaller than that of the superconducting wire connected to the squid loop.
