Improving Resolution and Run Outs of a Superconducting Noncontact Device for Precision Positioning

This paper describes the improvement of the performance of a long-stroke high-precision positioning slider suitable for cryogenic environments due to the application of a set of design rules given in a previous paper. The device, based on superconducting magnetic levitation, is self-stable and does notmake contact between the slider and the guideline, avoiding tribological and lubrication problems associated with cryogenics.
