摘要：
A noncontact stable linear suspension is proposed for a ring-shaped superconducting coil in the magnetic field of two other stationary ring-shaped superconducting coaxial coils. The suspended coil is located between the stationary coils. To measure the displacement of the suspended coil, the stationary coils are connected in parallel and a low-inductance measuring coil is placed in the circuit between the connection points. The current in the measuring coil varies according to a linear law as the suspended coil is displaced along the common axis of the stationary coils. The characteristics of the instrument based on such a suspension are numerically evaluated. Due to the absence of a displacement meter as a separate unit, it is possible to simplify the design of the instrument to the maximum extent and exclude the reverse effect of the displacement meter on the suspended coil.
