Abstract
An example particle accelerator includes a coil to provide a magnetic field to a cavity; a cryostat comprising a chamber for holding the coil, where the coil is arranged in the chamber to define an interior region of the coil and an exterior region of the coil; magnetic structures adjacent to the cryostat, where the magnetic structures have one or more slots at least part-way therethrough; and one or more magnetic shims in one or more corresponding slots. The one or more magnetic shims are movable to adjust a position of the coil by changing a magnetic field produced by the magnetic structures.
