摘要：
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.
