Abstract
Glaser magnets used for focusing charged particle beams show appreciable ab errations. These aberrations can be reduced by increasing the pole gap, whi ch, however, reduces the focal power also. We have shown that a better way of improving the field quality in Glaser magnets is to taper the poles outw ards. The saturation characteristics also are better in tapered poles.
