Abstract:
Several new high brilliance lattices of the HLS storage ring are proposed. The magnetic lattices are designed with the constraints that the positions of all the elements and beamlines in the storage ring are kept unchanged and no new element is used. Small beam emittances can be achieved step by step. In these lattices, all of the straight sections have small vertical beta function, which are suitable for the operation of insertion devices. Tracking study shows that the new lattices have sufficiently large dynamic apertures for injection and storage.
