The Main Storage Ring For the new lattice the so-called "TME-Optic" has been adopted, which gives the smallest emittance and the highest percentage of the circumference for insertion devices. The storage ring has 8 Super Periods with 2 x 22.5 degree bending magnets. The basic elements of the lattice are combined function bending magnets, with a set of quadrupoles and sextupoles on each side of the bending magnet, in order to provide the proper focusing and the chromatic correction for the beam. 12 straight sections are available for insertion devices with lengths up to 3.9 meters. 12 Available Straight Sections for Insertion Devices 828 x 21
