Abstract:
Designing steel-dominated high-field quadrupoles one finds that saturation effects cause a considerable reduction in field quality, i.e., an increase in DeltaB(theta, B-0)/B-0 = [B-y(real)(B-0, theta) - B-y(ideal)(theta)]/B-y(ideal)(theta) with all flux densities taken for different azimuthal angles 0 along a circle of radius r within the quadrupole aperture. Some improvements can be achieved by additional corrective-coils the current through which is not a constant percentage of the current through the main coils but a percentage that varies with the maximal pole-tip flux density Bo in the quadrupole. A considerably greater improvement can be obtained, however, when voids are formed inside the magnet poles close to their tips. Using such voids field qualities of a few hundredth of 1% can be achieved over all azimuthal angles theta for pole-tip flux densities less than or equal to1.5 T.
