Abstract: Many synchrotron radiation facilities are studying lattice upgrades in order to lower the natural emittance and hence increase the radiation brilliance and transverse coherence. While large circumference rings are favoured for reaching ultra small emittance, recent advances in design and optimisation tools allow also medium size rings to reach emittances down to the some 100s of pm region, with workable lattices. Diamond is investigating a novel design whereby low emittance is conjugated with doubling of the capacity of the ring based on a double-double bend achromat (DDBA cell). Plans for the installation or one or more low emittance cells will be presented. this will serve as a prototype for a possible full phased upgrade of the storage ring in the longer term.
