Just like other new light sources, longitudinal gradient bending magnet (LGB) will be adopted to suppress the beam emittance. The magnet consists of 7 modules with different magnet-ic field. Each module has yoke and poles with the same size but different amount of permanent magnet to gener-ate field gradient. FeNi alloy is used to shunt magnetic flux and thus improve the temperature stability. Correc-tor coil or movable wedge can be used to adjust the field. Impact of magnetization direction error of permanent magnet block and parallelism error of poles on multi-poles is also evaluated.
