<p>A pick-up coil assembly, for a multi-channel SQUID magnetometer, includes: a base plate (62); a plurality of support bars (61) 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 (50) having respective first and second pick-up coil blocks. Each of the blocks has a support body (50a, 50b), a pair of pick-up coils (52a,...52d), connection pads (54a,...54f) and connection lines (53a, 53b), the pair of pick-up coils, the connection pads and the connection lines being formed on the support body using lithography techniques. Such a pick-up coil assembly can be made to a desirably high precision, whereby the detection characteristics of the different coils can exhibit improved uniformity.</p> |
