The National Synchrotron Light Source II (NSLS-II) under construction at Brookhaven National Laboratory will be a new state-of-the-art 3 Gev electron storage ring designed to deliver world-leading intensity and brightness, and will produce x-rays more than 10,000 times brighter than the current NSLS at Brookhaven. The 792-meter circumference storage ring is comprised of approximately 1000 magnetic elements, 300 of which are discrete corrector magnets. The three variants are: 120 of the 100 mm aperture correctors, 60 of the 156 mm aperture correctors, and 90 of the air core correctors.[1] The 100 mm and 156 mm horizontal and vertical dipole correctors come in two varieties: with and without a DC skew quad corrector. The air core is strictly an AC horizontal and vertical dipole corrector. The specifications are listed. Discrete corrector magnets are used for the 230 horizontal and vertical steering magnets in the NSLS-II storage ring. A unique design incorporates both dipole and skew quad correctors for (DC) steering in the same magnet. Separate AC (orbit feedback) correctors have also been designed. Comparison with alternate designs are presented as well as prototype measurements.
