Precision magnet movers for the Final Focus Test Beam

Fully automated movers capable of positioning beamline magnets weighing more than 100 kg to a few microns over several millimeters have been designed and built for the Final Focus Test Beam at SLAC. These movers also provide incremental motion as small as a few tenths of a micron. We review the basic design considerations, the hardware realization of the movers, and the extensive tests conducted on these electromechanical stages. Suggestions for the improvement and augmentation of such movers are also given.
