Design and performance of the dipole magnet for the SRRC storage ring

22 combined function dipole magnets have been fabricated for the SRRC storage ring. The dipole magnet is a curved shaped with rectangular edges which creates a nominal field strength of 1.2407 Tesla and a gradient strength of 1.71 T/m along the magnetic center at 1.3 GeV. The errors of dipole and quadrupole fields in the radial direction is within /spl plusmn/1/spl times/10/sup -4/ and /spl plusmn/2/spl times/10/sup -3/ over the useful aperture. The deviations of the integrated dipole field and the quadrupole field strength for all the 22 magnets are smaller than /spl plusmn/1/spl times/10/sup -3/ and /spl plusmn/2/spl times/10/sup -3/, respectively. Shims with thickness 3 mm are added on each pole edge for correcting the sextupole component in the end fringe field.<>
