SSRF beam line phase II project
In SSRF beam line phase II project there are 16 beam lines will be built. Besides, the storage ring will be improved. Two of the cells will be modified by using superbends to create two short straight sections. Two long straight sections will modified to double mini beta_y function lattice by adding a triplet in the middle for each. Also a superconducting 3rd harmonic cavity will be added to lengthen the bunch length, several types of insertion devices are developed to provide radiations under users’ requirement.
