The storage ring has a nominal operating energy of 800MeV and a circumference of 66.13m. It consists of 8 bending magnets, 32 quadrupole magnets and 32 multifunctional sextupole magnets. The storage ring has 8 straight sections, one of which is used to install the storage ring injection system to inject the injector beam into the storage ring, one is used to install the high-frequency system to supplement the synchrotron radiation energy loss of the electron beam, and the other 6 straight sections can be installed with different types of insertion elements according to the needs of synchrotron radiation experiments. The length of the straight section accounts for 38% of the storage ring, reaching the international advanced level.
