Abstract :
The recent upgrade of the NSLS X-Ray Ring energy from 2.584 to 2.8 GeV requires defocusing sextupole fields beyond the operating limits of the present sextupole magnets. We have demonstrated that the required fields can be achieved by addition of permanent magnets to counteract the saturation in the magnet poles. Magnetic measurements on a NSLS sextupole agree with fields predicted by Radia
