ABSTRACT:
A pick-up coil assembly for a multi-channel SQUID magnetometer. The assembly includes a base plate, a plurality of support bars fixedly mounted on the base plate so as to form a matrix, and a plurality of pick-up coil units fixedly mounted on the support bars, each pick-up coil unit having a first and second pick-up coil block. Each of the pick-up coil blocks has a support body, a pair of pick-up coils, connection pads and connection lines. The pair of pick-up coils, the connection pads and the connection lines are formed by a lithography technique on the support body.
