Abstract :
The Superconducting Super Collider magnet coil has three wedges separating the superconducting coil blocks on its inner layer. It is shown how if the wedges have superconductors attached, one can correct all of the magnetic field multipoles (both normal and skew) from N=1 (dipole) to N=6 (12 pole). Wedge correction winding orientation, dimensions, and peak currents needed are described. The tradeoff required for using this correction method is additional complication of the dipole magnets and additional He refrigeration needed to cool the extra magnet leads. This refrigeration can be reduced by putting the wedges in six dipole magnets in series. However, wedge correction will result in the elimination of continuous bore-tube correction coils and it could result in simplification of the SSC lumped correction magnet system.
