<p>A pick-up coil assembly for a multi-channel SQUID magnetometer comprises a pair of support plates (120a, 120b), each support plate having a centre penetrating hole and a plurality of penetrating holes (1201) arranged in an array configuration; a support bar (123) for fixedly mounting each support plate (120a, 120b) through the centre penetrating hole (1201); a plurality of coil base plates (121) provided on each support plate, each coil base plate having a penetrating hole (1212), a pick-up coil (1211) and connection pads (1213), and the pick-up coil and the connection pads being formed by a lithography technique; and superconductive wires (122) for connecting between a pick-up coil of the upper support plate (120a) and a corresponding pick-up coil of the lower support plate (120b) through the penetrating hole, to form a first order or second order gradiometer. <IMAGE></p> |
