Recent developments in the DIAMOND storage ring design

The Design Phase of DIAMOND, a 3rd generation light source facility, is currently in progress. Earlier studies of a similar storage ring had found a basic lattice structure with low emittance, good dynamic stability and the flexibility to operate in different modes. The lattice has been further developed to meet the evolving demands of the project, delivering very high brightness radiation over a wide photon energy range. Optimisation of the lattice properties, including those of nonlinear dynamics, is described in detail, together with other general characteristics of the storage ring.
