Abstract
A passive shimming system for a superconducting magnet to improve bore magnetic homogeneity includes a plurality of axially extending non-magnetic drawers each including a plurality of pockets along the drawer with a securable cover for each pocket to enclose the selected ferromagnetic shim disks and compressible spring material to enable individual access and shimming of selected pockets.
