摘要
研制了适用于电偶源瞬变电磁法中直接测量磁感应强度B的高温超导磁强计,并进行了电偶源瞬变电磁法大地电磁测量野外实验。测量结果表明了高温超导磁强计明显优于常规感应线圈探头,可以得到更深的探测深度。
The HTc SQUID magnetometer is characterized by relatively low noise,wide frequency range,high-response to low frequency and can thus be used as a B field sensor in LOTEM.The results of the field tests of HTc SQUID applied in LOTEM show that the HTc SQUID magnetometer has superiority over conventional inductive coil.Applying the HTc SQUID in LOTEM will promote the depth of investigation,and it can thus serve as a new instrument in geophysical exploration of the deep resource.
