摘要：

Superconducting Quantum Interference Devices (SQUID) are highly sensitive sensors for magnetic flux. These sensors have been recently utilized for Time Domain Electromagnetic (TDEM) systems for geophysical applications. In view of this, a program has been initiated at IGCAR to develop SQUID based TDEM system suitable for geophysical explorations. For this work, SQUID sensors with fast FLL system, transmitter, transmitter controller and data acquisition system have been integrated. A metal object has been detected by using the SQUID based TDEM system by recording the flux profile as the object is moved relative to the SQUID system. This paper describes the development, characterization and performance testing of the system.
