The overwhelming majority of SQUID magnetometer systems involve the use of superconducting pick-up coils connected through superconducting contacts to planar DC SQUIDs. These devices must, in turn, be connected through low resistance leads to superconducting impedance matching tuned or transformer circuits. This requires a fully elaborated superconducting technology (junctions, multilayer structures, wire, bulk shielding, superconducting contacts and low resistance contacts to the superconducting bulk and film). The advantage of such a system is that liquid helium can be eliminated as the coolant. The (Image Omitted) disadvantage is that the energy resolution scales with the ambient temperature.
