Magnetic measuring apparatus and geological survey system using the same

摘要

PROBLEM TO BE SOLVED: To realize a highly sensitive magnetic measurement in which foreign noises can be reduced by a magnetic measuring device using a superconductive magnetic sensor.;SOLUTION: The magnetic measuring device includes: a low temperature holding container; a cylindrical magnetic shield in the low temperature holding container having an open end and a closed end; a superconductive magnetic sensor in the magnetic shield; and a coolant filled in at least between the low temperature holding container and the magnetic shield.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
