Tests of cryogenic SQUID for geomagnetic field measurements. Final report

Technical Report ·
OSTI ID:7256947
A type of cryogenic SQUID (superconducting quantum interference device) magnetometer was designed for geomagnetic measurements. Field tests of the instrument including comparisons to observatory variometers, a rubidium magnetometer, an induction loop, and a fluxgate magnetometer showed the new cryogenic systems to be reliable, accurate, portable and simple to operate. Directional measurements of natural magnetic field fluctuations as small as 0.0001 gamma with periods from 0.5 sec to several hours were demonstrated.
