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. The authors 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.
