Abstract
A precision magnetic manipulator for use in positioning targets, and the like, within a vacuum chamber, employs separate mechanisms for linear and rotational motion and makes them substantially independent. Ball or roller style bearings support a square, linear shaft within a housing, at least one set of bearings being at the point at which the shaft exits the housing, and another set being within the housing along the route of travel of the linear shaft, so that the shaft is fully being supported over the entire travel length. A magnet carriage supporting high-strength magnets, one system being optimized for rotational motion and the other being optimized for linear motion, couples to magnet followers within the housing, thereby providing rotational motion and linear motion which can be used in combination or separately, giving great freedom of movement within the vacuum chamber.
