The invention relates to super-sensitive magnetic measurements. A device for mechanical balancing a superconductor gradiometer includes three drives of displacement for balancing gradiometer by 3 orthogonal, in particular: longitudinal and two cross components of magnetic field, for realization of separate displacement of three short-circuit superconductive trim-rings made of different superconductive materials along the axis of the cylindrical body of axial wire gradiometer of second order that includes a receiving turn, two middle and one upper compensation turns placed at the lower end, at the middle of the body and at the upper end, respectively, at distance equal to the base of gradiometer. The technical result of the invention is in achieving the level of balance up to 20 ppm by all the components, enough for measurement in unscreened conditions, simplification and speed-up of the procedure of balancing due to minimization of deterioration of the degree of balance by two components at adjustment by the third one, possibility of use of the device to multi-channel systems and at its mobile realization. |
