摘要：

HTc SQUID magnetometer is characterized by low noise, high sensitivity, wide dynamic and frequency ranges and can be used as a B field sensor. Theoretically, the HTc RF SQUID magnetometer has superiority over conventional inductive coil in TEM application. Since 1989, Bejing University and IGGE have been developing HTc SQUID magnetometers for geophysical exploration. We have manufactured the HTc SQUID magnetometer adapted to several commercial TEM system, and realized measuring magnetic field directly in TEM. IGGE also have studied the data processing and interpretation technology and have developed resistivity imaging software for the data acquired with HTc SQUID magnetometer. The results of the field tests show that larger detection depth could be expected in TEM survey by using HTS RF SQUID magnetometer.
