Abstract :
The magnet lattice of the SRRC (Synchrotron Radiation Research Center) 1.3 GeV low-emittance synchrotron light source is presented. The lattice consists of six identical cells. Each cell has a triple-bend-achromat arc and a 6-m dispersion-free long straight section. Quadrupole triplets between the achromat arc and long straight section are employed for tune and beta matching. The ring circumference is 120 m. Bending magnets in the arc are with vertically focusing gradient components. Such combined function magnets can reduce vertical beta function and hence the vertical aperture is small. The emittance is 1.92*10/sup -8/ mrad at 1.3 GeV. Two families of sextupoles are used for chromaticity correction and good dynamic aperture can be achieved.<>
