| Abstract: | 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. |
