摘要
高温超导磁强计具有直接测量磁场、低噪声、高灵敏度、动态范围大、频带宽低频响应好的特点,可以取代感应线圈作瞬变电磁法的接收传感器。在理论上,高温超导磁强计应用在瞬变电磁法中具有优势。以高温超导磁强计作收传感器和以感应线圈作收传感器,在瞬变电磁法上进行了大量的野外对比试验,结果表明:把高温超导磁强计应用于瞬变电磁法(TEM)勘探上,能够加大勘探深度。
The HTS RF SQUID magnetometer is characterized by low noise, high sensitivity, and wide dynamic and frequency ranges. It can therefore be used to measure the magnetic field directly. Theoretically, the HTS RF SQUID magnetometer has superiority over the conventional inductive probe in TEM application. The tentative TEM survey for comparison was carried out in field by using HTS RF SQUID magnetometer and induction, and the results show that larger detection depth could be expected in TEM survey by using the HTS RF SQUID magnetometer.
