JESSY DEEP is the world's most sensitive receiver for transient electromagentic (TEM) measurements. The most common application is in the exploration of minerals. By the help of a coil; transients are excited in the ground. The detection of the decaying signal allows evaluating conducting material underneath. The SQUID's unrivalled sensitivity provides the exploration community with data of deeper targets or ore bodies covered with a conducting overburden then conventional receivers. The exceptionally high dynamic range of JESSY DEEP results in shorter data acquisition times and ultimately more efficient measuring campaigns.
Advantages of using SQUID based EM receivers:
◇ Direct measurement of the magnetic field
◇High magnetic field resolution at low frequencies
◇ Flat frequency response from dc up to 10 kHz
