The recently upgraded (Oct 2002) 2G Superconducting Rock Magnetometer is located in a magnetically shielded environment in the Second Floor Paleomagnetism Laboratory in Northrop Hall at the University of New Mexico. The “Low Field Room” essentially negates Earth’s magnetic field. The shielding is accomplished with two layers of mu-metal, forming a rectangular inner room of approximately 10 feet by 20 feet with residual fields ranging from 100 nT to less than five.

Along the west side of the shielded environment, oriented such that the long-axis of the instrument is parallel to Earth's magnetic field lines, is the 2G Enterprise superconducting rock magnetometer with a background noise sensitivity of 5 x 10-14 Am² per axis.

The unit is interfaced with a 2G Applied Physics alternating-field demagnetization unit, with an automatic sampler handler that can perform progressive, three-axis, alternating-field demagnetization experiments automatically up to peak fields of 140 mT

The ~ 50 sample Shaw furnace permits large-volume demagnetization of redbed sediments and other rock types. This unit is capable of maximum laboratory unblocking temperatures of 680 degrees Celsius. The unit is located in the second floor lab opposite the magnetometer.

A small-volume magnetically shielded Schonstedt furnace is located in the Basement Paleomagnetism-Rock Magnetism Lab, permitting thermal demagnetization of up to 20 paleomagnetic specimens with a cycle time of about one hour.
